That would have been the obvious fix to make in the first place, I was
lazily assuming it hadn't worked (and there was some grumbling about crashes
with some versions of lex/flex...).

Your simpler version works for me.

I don't have the original DTD file with the names beginning with caps, bug I
just nobbled one or 2 fields of an existing file.  The parsing doesn't fail,
but the capitalisation doesn't show in the Filter Expression editor with
either version.  I don't know if it would be able to match the filter with a
field that showed the capitalisation...

Anyway, I think your version should be applied.
