Controls whether a xmlns="http://example.com" default namespace prefix
definition will be provided for the embedded schema.
This matters when the defined schema is used to validate the infoset xml
before unparsing, or after parsing, as it affects the interpretation of
path expressions in the DFDL schema based on the unqualifiedPathStepPolicy
tunable.
False is recommended since default namespaces can be confusing.
Not to be confused with dfdl:byteOrder, this attribute describes the
order of bits or bytes in the TDML document part, that is, whether
they
should be given their positions starting from the beginning (LTR) or the
end (RTL). LTR is the normal default where data location number
increase
from left to right. RTL is used for bit-order LSBFirst, and the bytes
are ordered starting on the right increasing to the left.
