      /PortTLS (The server knows whether or not the client is using TLS by the first byte of the request.)
      /MIME (Support for MIME types is provided for compatibility; ULFI is preferable.)
      /LanguageResponse (Language can allegedly be specified in the file format, but the specification is incomplete.)
      /AbstractMetadataRequest (May be added in future (unsure).)
      /LinkRelations (This feature is optional.)
      /ListNesting (There is no actual "list" type, although the control character 0x02 can be used to delimit list numbers/bullets from the text, and can occur more than once.)
      /Favicon (Only possible when TLS is used. Clients MUST allow favicons to be disabled (or not implement favicons at all).)
      /InlineFormatting (Limited; only "normal", "emphasis", "strong", "fixpitch", and the exact meanings are deliberately not defined by the specification.)

      /LinkRelations (The relations are different from HTML.)
      /UniversalDecimalClassification (Class 4 is not currently defined in UDC, but Scroll uses it to mean anything that doesn't fit in the other classifications (including no class at all).)
