HTML4 was backwards-compatible.  XHTML2 is explicitly not.

The technique might work, the particular implementations will not.  Even 
when the installed user-base of XHTML2 user-agents is at 90% or so, there 
will still be the 10% that need an older version, unless you propose 
writing "backwards-compatible" XHTML2?
