Of course every child of an <mlabeledtr> is an <mtd>.  Perhaps I
misunderstood the original issue.  In saying "special case the first"
I was speaking about the restricted nature (for labelling) of content
in the first <mtd> of an <mlabeledtr>.  That cannot be enforced by a
dtd.  Since it's not really a cell, it should have a different name
such as, for example, "mtag" in MML3.
