DSD 2.0 description of XHTML1.0-Transitional
This description differs from the DTD version in the following
ways, as annotated with meta attributes from the namespace
http://www.brics.dk/DSD/2.0/meta:
This description captures some requirements that only
appear as comments in the DTD. These extensions are marked
by "non-DTD" attributes.
All input field attribute declarations are marked
with "input-field".
Elements and attributes that are deprecated in the
XHTML 1.0 / HTML 4.01 specification are marked by
"deprecated" attributes.
IDREFS cannot be expressed - these are marked with
"idrefs".
