Good, somehow the old behaviour went against my intuition, ;-)

BTW, the test suite /dev/tests/ is fascinating.  Maybe mention
it on a more prominent page like /docs/ or /docs/users.html (?)

I've found an interesting difference between the W3C and the
WDG validators:  In one of my documents I've "included" some
symbolic MathML character entity references.  This worked with
both validators.  I've then changed the URL of the entity sets
to the corresponding validator.w3.org/sgml-lib files, because
I use this directory in all DOCTYPE elements.

I've no idea why some entity sets exist three times there, e.g.
/sgml-lib/UPD-MathML2-20021015/isotech.ent
/sgml-lib/UPD-MathML2-20021015/iso8879/isotech.ent
/sgml-lib/UPD-MathML2-20021015/iso9573-13/isotech.ent

The latter is apparently the file used in the MathML DTD.  But
because I only wanted a quick hack defining some entitities in
an XHTML transitional document, I first tested the version in
/sgml-lib/UPD-MathML2-20021015/isotech.ent

The W3C validator accepted this.  But the WDG validator didn't
like the <!ENTITY &imped; "&#x1D543;"> in this file.  I don't
need &imped; in my document and use again the "better" version
/sgml-lib/UPD-MathML2-20021015/iso9573-13/isotech.ent

For some time the W3C validator did not more accept character
references like &#128; - now this works again (resulting in a
warning instead of an error).  Too late, I finally understood
the difference between &#128; and byte 128 in a windows-1252
document (after two years... ouch ;-)

But if you want a really weird test case with windows-1252
characters and MathML 2.0 entitities in a "compatible" XHTML
document rip <URL:http://purl.net/xyzzy/ibm850.htm>

                  Bye, Frank

P.S.: "compatible" ~ 1.1 + attributes align and name... <gd&r>
