I was just echoing language from the SIG's own home page. 
We don't need 
it to be the best language for XML processing, but it's the
language we 
use for much of our administrative interfaces and all of our
data 
exchange arrangements.

That's what we did, and that package (the one the SIG
recommended) has 
been abandoned in favor of a newer one.  It would be nice if
we could 
reduce the chance of that happening again by having the
package 
incorporated into the standard library.

Well, if you have customers (as we do) who have entered into
data 
exchange arrangements with other organizations and companies
with 
agreements to make sure that the documents exchanged meet
sets of 
validation rules, then it seems that the choice you have is
to use an 
existing XML validation package or to write your own XML
validation 
software.  We'd rather not re-invent the wheel, but we'd
also like to 
avoid repeatedly replacing third-party packages as they are
abandoned.

That's not exactly true. It hasn't been abandoned in favor
of lxml, or
some other package. It has been abandoned in favor of the
standard
library (at least, that's why *I* abandoned it; not sure why
nobody
was picking it up).

PyXML *is* integrated into the standard library. Just use it
there.

One option, of course, is to take over maintenance of a
package that
was abandoned. This is free software.
