I think the license says that it may be freely used to make derived
works that implement what it describes (the entities). But my brains
does become a bit fuzzy when reading this copyright statement.

Does anybody think this is not free and/or GPL compatible?

If anybody objects then maybe we can use the ones from the XHTML spec?
<http://www.w3.org/TR/2000/REC-xhtml1-20000126/#dtds>

But the simplest solution might be to just clean the original HTML from
those entities when transforming to XML. I believe there are only about
200 valid/used symbols anyway.

I don't know. We might have to ask the gnu webmasters
(address@hidden). Should there be an actual dtd at that address?

Speaking of which. Since we still don't have a dtd can we also use the
--novalid flag for xsltproc so we won't get the warning messages about
missing dtds?
