Maybe.  I've done some battle with DOM::XML:: in Perl.  It may be ok
if you want to parse XML-encoded documents; that's what it appears to
be for.  But the documentation is very feeble, and I found it to be a
nightmare when I tried to use it to parse something that wasn't a
document.   So I wouldn't necessarily say that XML Is "supported" in
Perl.  

Maybe the Python XML package is better -- gotta try that one of these
days. 

BER/DER is that it's very simple, so even if the support isn't there
yet that may not be a big issue.

Exactly.  Conversely, ASN.1 has good data type support, including
binary types of all kinds.
