Earlier_JJR summary_NN of_IN the_DT problem_NN 
------------------------------_: A_DT generic_JJ mechanism_NN for_IN counters_NNS ,_, including_VBG some_DT rules_NNS for_IN presentation_NN of_IN counters_NNS ,_, is_VBZ as_IN follows_VBZ ._. 
-_: Every_DT type_NN of_IN numbered_VBD object_VBP ,_, table_NN ,_, figure_NN ,_, equation_NN ,_, reference_NN ,_, has_VBZ its_PRP$ own_JJ counter_NN ._. 
-_: All_DT top-level_JJ counters_NNS start_VBP at_IN the_DT value_NN 0_CD (_( zero_CD )_) at_IN the_DT beginning_NN of_IN the_DT document_NN ._. 
-_: If_IN nesting_JJ is_VBZ possible_JJ ,_, every_DT nesting_JJ level_NN has_VBZ its_PRP$ own_JJ counter_NN ._. 
-_: Counters_NNP of_IN levels_NNS below_IN top-level_JJ start_NN at_IN the_DT value_NN 0_CD (_( zero_CD )_) at_IN the_DT start_NN tag_NN of_IN the_DT next_JJ higher_JJR (_( parent_NN )_) level_NN ._. 
-_: From_IN the_DT values_NNS of_IN the_DT counter_NN (_( s_VBZ )_) a_DT label_NN is_VBZ calculated_VBN ._. 
This_DT label_NN is_VBZ e.g._NN printed_VBN in_IN the_DT article_NN as_IN it_PRP appears_VBZ in_IN a_DT journal_NN issue_NN ._. 
The_DT relation_NN between_IN labels_NNS and_CC counters_NNS is_VBZ application-dependent_JJ ._. 
Example_NN :_: |_NN <_NN sec_NN id_NN =_SYM "_'' 99_CD "_'' >_NN |_NN could_MD be_VB printed_VBN as_IN `_`` `_`` 3.2_CD .1_CD '_POS '_POS ._. 
-_: The_DT values_NNS of_IN the_DT |_NN id_NN |_NN attributes_NNS are_VBP unique_JJ within_IN the_DT document_NN instance_NN ._. 
-_: The_DT |_NN id_NN |_NN attribute_VBP is_VBZ not_RB identical_JJ to_TO the_DT counter_JJ value_NN ._. 
-_: If_IN the_DT |_NN id_NN |_NN attribute_VBP is_VBZ missing_VBG ,_, the_DT counter_NN is_VBZ not_RB incremented_JJ ,_, and_CC the_DT element_NN is_VBZ not_RB numbered_VBN ._. 
This_DT allows_VBZ for_IN e.g._NN un-numbered_JJ equations_NNS ._. 
This_DT means_VBZ that_IN tables_NNS and_CC figures_NNS always_RB have_VBP an_DT |_NN id_NN |_NN attribute_VBP even_RB when_WRB they_PRP are_VBP not_RB referenced_JJ ._. 
(_( Or_CC are_VBP there_EX also_RB cases_VBZ where_WRB tables_NNS and_CC figures_NNS are_VBP not_RB numbered_VBN ?_. )_) 

There_EX are_VBP (_( at_IN least_JJS )_) the_DT following_VBG exceptions_NNS to_TO the_DT algorithm_NN described_VBD above_IN :_: 
1_CD ._. The_DT contents_NNS of_IN a_DT figure_NN form_NN one_CD (_( physical_JJ )_) entity_NN ,_, but_CC inspection_NN of_IN the_DT contents_NNS show_VBP that_IN there_EX are_VBP logical_JJ sub-figures_JJ (_( hidden_VBN )_) inside_IN the_DT figure_NN ._. 
Example_NN :_: the_DT contents_NNS of_IN figure_NN ~_NN 2_CD contains_VBZ markers_NNS `_`` a_NNP '_'' ,_, `_`` b_SYM '_'' and_CC `_`` c_SYM '_'' ,_, which_WDT indicate_VBP logical_JJ sub-figures_JJ 2_CD a_DT ,_, 2_CD b_SYM and_CC 2_CD c_SYM ._. 
2_CD ._. Normal_NNP equation_NN numbering_VBG (_( 1_CD ,_, 2_CD ,_, 3_CD ,_, ..._... )_) is_VBZ interrupted_VBN by_IN an_DT equation_NN number_NN that_WDT is_VBZ `_`` derived_VBN from_IN '_POS an_DT earlier_JJR one_CD ._. 
Example_NN :_: (_( 1_CD )_) ,_, (_( 2_CD )_) ,_, (_( 3_CD )_) ,_, (_( 1_CD '_POS )_) ,_, (_( 4_CD )_) ,_, (_( 5_CD )_) ,_, ..._... 
3_CD ._. Numbering_NNP in_IN lists_NNS ,_, or_CC sub-numbering_JJ in_IN equations_NNS ,_, is_VBZ interrupted_VBN ._. 
Example_NN :_: a_DT numbered_JJ list_NN with_IN items_NNS 1_CD ,_, 2_CD ,_, 3_CD ,_, is_VBZ followed_VBN by_IN a_DT paragraph_NN of_IN text_NN (_( the_DT |_NN |_NN is_VBZ on_IN the_DT same_JJ level_NN as_IN the_DT |_NN <_NN l_NN >_NN |_NN )_) ,_, and_CC then_RB the_DT list_NN continues_VBZ 4_CD ,_, 5_CD ,_, 6_CD ._. 
The_DT intention_NN of_IN the_DT author_NN appears_VBZ to_TO be_VB {_( \_NN em_NN one_CD \_NN /_NN }_) list_NN ,_, but_CC this_DT list_NN is_VBZ interrupted_VBN ._. 
A_DT similar_JJ example_NN can_MD be_VB found_VBN in_IN equation_NN sub-numbering_JJ :_: equations_NNS (_( 4_CD a_DT )_) and_CC (_( 4_CD b_SYM )_) are_VBP followed_VBN by_IN a_DT paragraph_NN of_IN text_NN ,_, followed_VBN by_IN equations_NNS (_( 4_CD c_SYM )_) and_CC (_( 4_CD d_SYM )_) ._. 

Below_NNP I_PRP will_MD discuss_VB each_DT case_NN separately_RB ._. 

Hidden_NNP sub-figures_JJ ------------------
_: When_WRB a_DT figure_NN (_( as_RB far_RB as_IN we_PRP know_VBP ,_, hidden_VBN sub-components_JJ occur_VB only_RB with_IN figures_NNS ._. )_) that_WDT exists_VBZ as_IN one_CD physical_JJ entity_NN consists_VBZ of_IN logical_JJ sub-entities_JJ ,_, the_DT only_JJ solution_NN lies_VBZ in_IN adding_VBG this_DT information_NN ,_, which_WDT lies_VBZ *_NN outside_JJ *_NN the_DT document_NN ,_, to_TO the_DT document_NN ._. 
One_CD possibility_NN for_IN this_DT is_VBZ to_TO give_VB the_DT |_NN <_NN fig_NN >_NN |_NN start_NN tag_NN a_DT new_JJ attribute_NN that_WDT specifies_VBZ the_DT labels_NNS of_IN the_DT individual_JJ components_NNS ._. 
This_DT enables_VBZ generation_NN of_IN the_DT labels_NNS of_IN the_DT sub-figures_JJ ._. 

First_CD an_DT example_NN of_IN a_DT regular_JJ case_NN :_: <_NN fig_NN id_NN =_SYM fig_NN 4_CD >_NN <_NN fig_NN id_NN =_SYM fig_NN 4_CD a_DT >_NN <_NN figlnk_NN file_NN =_SYM "_'' fig_NN 4_CD a_DT "_'' >_NN <_NN /_NN fig_NN >_NN <_NN fig_NN id_NN =_SYM fig_NN 4_CD b_SYM >_NN <_NN figlnk_NN file_NN =_SYM "_'' fig_NN 4_CD b_SYM "_'' >_NN <_NN /_NN fig_NN >_NN <_NN /_NN fig_NN >_NN 

Here_RB the_DT outer_JJ figure_NN and_CC the_DT two_CD nested_JJ figures_NNS each_DT have_VBP their_PRP$ own_JJ unique_JJ key_NN for_IN referencing_VBG (_( fig_NN 4_CD ,_, fig_NN 4_CD a_DT ,_, fig_NN 4_CD b_SYM )_) ,_, and_CC we_PRP have_VBP the_DT following_VBG (_( id_NN ,_, label_NN )_) pairs_NNS :_: (_( fig_NN 4_CD ,_, 4_CD )_) (_( fig_NN 4_CD a_DT ,_, (_( 4_CD 1_CD )_) )_) (_( fig_NN 4_CD b_SYM ,_, (_( 4_CD 2_CD )_) )_) where_WRB the_DT counter_NN strings_NNS (_( 4_CD 1_CD )_) and_CC (_( 4_CD 2_CD )_) are_VBP represented_VBN as_IN `_`` 4_CD a_NNP '_POS and_CC `_`` 4_CD b_SYM '_POS (_( but_CC this_DT presentation_NN is_VBZ application-dependent_JJ of_IN course_NN )_) ._. 

Second_JJ an_DT example_NN of_IN hidden_VBN sub-figures_JJ :_: <_NN fig_NN id_NN =_SYM fig_NN 4_CD >_NN <_NN figlnk_NN file_NN =_SYM "_'' fig_NN 4_CD "_'' >_NN <_NN /_NN fig_NN >_NN the_DT picture_NN in_IN |_NN fig_NN 4_CD |_NN contains_VBZ two_CD labels_NNS ,_, `_`` a_NNP '_'' and_CC `_`` b_SYM '_'' ,_, that_WDT identify_VBP sub-figures_JJ ._. 
Both_DT the_DT figure_NN as_IN a_DT whole_JJ and_CC the_DT individual_JJ sub-figures_JJ are_VBP referenced_JJ ._. 
If_IN we_PRP add_VBP an_DT attribute_VBP to_TO the_DT start_NN tag_NN we_PRP can_MD achieve_VB this_DT :_: |_NN <_NN fig_NN id_NN =_SYM fig_NN 4_CD comp_NN =_SYM "_'' a_DT b_SYM "_'' ^_NN gt_NN ;_: |_NN ._. 
The_DT keys_NNS `_`` fig_NN 4_CD a_NNP '_POS and_CC `_`` fig_NN 4_CD b_SYM '_POS are_NN implied_VBN (_( automatically_RB generated_VBN )_) ;_: these_DT implied_JJ keys_NNS act_VBP as_IN aliases_NNS for_IN `_`` fig_NN 4_CD '_POS ,_, since_IN they_PRP refer_VBP to_TO the_DT same_JJ physical_JJ object_VBP ._. 
Unfortunately_RB ,_, the_DT attribute_NN |_NN comp_NN =_SYM "_'' a_DT b_SYM "_'' |_NN also_RB suggests_VBZ a_DT presentation_NN ._. 
Now_RB we_PRP have_VBP the_DT following_VBG (_( id_NN ,_, label_NN )_) pairs_NNS :_: (_( fig_NN 4_CD ,_, 4_CD )_) (_( fig_NN 4_CD a_DT ,_, (_( 4_CD 1_CD )_) )_) (_( fig_NN 4_CD b_SYM ,_, (_( 4_CD 2_CD )_) )_) where_WRB |_NN 4_CD |_NN ,_, |_NN (_( 4_CD 1_CD )_) |_NN and_CC |_NN (_( 4_CD 2_CD )_) |_NN refer_VBP to_TO the_DT same_JJ object_VBP (_( physical_JJ figure_NN )_) in_IN the_DT document_NN instance_NN ._. 

Derived_NNP equation_NN numbers_NNS ------------------------_: We_PRP illustrate_VBP this_DT case_NN with_IN an_DT example_NN ._.

In_IN that_DT case_NN we_PRP have_VBP the_DT following_VBG (_( id_NN ,_, label_NN )_) pairs_NNS for_IN the_DT first_JJ three_CD equations_NNS :_: (_( eq_NN 1_CD ,_, 1_CD )_) (_( eq_NN 2_CD ,_, 2_CD )_) (_( eq_NN 3_CD ,_, 3_CD )_) 

The_DT next_JJ equation_NN should_MD have_VB an_DT (_( id_NN ,_, label_NN )_) pair_NN like_IN this_DT :_: (_( eq_NN $_$ 1_CD ,_, label_NN (_( eq_NN 1_CD )_) '_POS )_) where_WRB |_NN eq_NN $_$ 1_CD |_NN is_VBZ the_DT unique_JJ |_NN id_NN |_NN assigned_VBN to_TO equation_NN ~_NN (_( 1_CD '_POS )_) ,_, and_CC |_NN label_NN (_( eq_NN 1_CD )_) |_NN stands_VBZ for_IN the_DT label_NN of_IN the_DT equation_NN with_IN id_NN =_SYM eq_NN 1_CD ._. 

And_CC the_DT next_JJ equation_NN ,_, (_( 4_CD )_) ,_, should_MD have_VB an_DT (_( id_NN ,_, label_NN )_) pair_NN like_IN this_DT :_: (_( eq_NN 4_CD ,_, 4_CD )_) 

The_DT question_NN is_VBZ whether_IN appending_VBG material_NN to_TO an_DT existing_VBG label_NN is_VBZ the_DT only_JJ form_NN of_IN derivation_NN ,_, or_CC whether_IN other_JJ forms_NNS of_IN derivation_NN exist_VB ._.

(_( Lists_NNP look_VB like_IN a_DT special_JJ case_NN of_IN nesting_JJ :_: numbering_VBG of_IN list_NN items_NNS normally_RB starts_VBZ with_IN 1_CD ,_, but_CC every_DT list_NN item_NN must_MD have_VB an_DT \_NN verb_NN |_NN id_NN |_NN that_WDT is_VBZ unique_JJ within_IN the_DT document_NN ._.
