R602 [Flexibility]
This specification should support common Presentation
Formats, which are in use today in Net-enabled applications. In particular,
it should support HTML, XHTML, WML and XML as Presentation Formats. It must
not preclude the use of other presentation formats (Eilon: such as Flash,
GIFs, etc.). Debate on last sentence: AK, CW.
I think only XML and HTML (due to its ubiquity) markups should be supported
by name, other formats should be considered opaque in the markup stream.
Last sentence should read:
It must not preclude the use of other presentation formats, although these
(e.g., Flash, GIFs, etc.) shall be considered opaque in the markup stream.
