Citations to anything aside from supposition? I find this incredibly hard 
to stomach.

So because much of the HTML-using public was under-educated about DTDs, 
let's forget about the distinctions?

There is a *significant* difference in strict <h2> and transitional <h2>. 
Presentational attributes are forbidden in the former, and allowed in the 
later. Yes, they are the same basic structure (a heading of level 2), but 
the allowable attributes are far from the same.

Remember, that XHTML 1.0 is the very first step in this project.
It is a reformulation of the *existing HTML 4.0 spec* (3 flavors), into 
XML. It does that.

No where in that spec does it say it will remain with three flavors forever.
