I don't think that support for XHTML5 should be optional. Specifying
that user-agents may support only one format, but supporting both is
"encouraged" is insufficient and will only lead to a lack of support for
XHTML5 like we had with XHTML1 [1]
We've been down this road before where support for application/xhtml+xml
was only an "opt in" for user-agents. That's the main reason we have
less than 100 valid XHTML websites today. [2]
People wont be able to use XHTML5 if there's no support for it.
Can this please be changed to:
[[
.....Implementations MUST support these two formats.
