It only recently came to my attention that HTML5 has reduced the content model
of TH to "phrasing content" (while leaving the content model of TD "flow
content").

This strikes me as odd in the extreme. Providing TH elements for their semantic
significance as table heads is useful and appreciated. But then limiting their
content model so that they are not as generally useful as TD elements appears
to take away that utility. Converting from, for example, CALS models where
block content is allowed in a table entry that occurs in a thead will mean
avoiding TH in favor of TD even when the cells are heads.

Given the surrounding thead, I suppose this is not that big a deal, except for
the fact that existing CSS stylesheets and JavaScript code may be relying on
the TH elements.

I encourage the WG to revert this change and allow flow content in TH as well
as TD.
