I thought XHTML transitional _is_ XML. In what way is XHTML transitional is a "less strict data format"?
It's a transition. It's a half-way house between HTML 4 and XHTML as it is intended (XHTML Strict).
No its not. There is no such thing as a half-way house between HTML 4 and XHTML.
XHTML defines "a reformulation of HTML 4 as an XML 1.0 application, and three DTDs corresponding to the ones defined by HTML 4" http://www.w3.org/TR/2002/REC-xhtml1-20020801/#abstract
The difference between a "strict" and a "transitionl" DTD (eg HTML4.01 Strict and HTML4.01 Transitional) is that the strict DTD has depreciated elements and attributes removed..
"Extensible HTML version 1.0 Transitional DTD -
This is the same as HTML 4 Transitional except for changes due to the
differences between XML and SGML."
