Understood. I really appreciate the help getting this to work.

Yes, I tried that first. If I don't place that argument in quotes, I
get this error:
Type error in argument 2 of SAX2XMLReader_setProperty, Expected
perl-string. at xerces_test.pl line 15.
When I do use quotes, I get the same error I reported earlier:
Type error in argument 3 of SAX2XMLReader_setProperty. Expected
_p_void at xerce s_test.pl line 15.

Hmmm ... it seems that, setting these as you suggest, I'm getting all
the errors when I use the MyErrorHandler cribbed from your code below
as my error handler, but I only get the first error when I use the
standard XML::Xerces::PerlErrorHandler.

It looks good to me.
[ ... code snipped ... ]
I'm getting another error which I guess is probably a Xerces-C
problem, but I want to mention it here in case it's got something to
do with Perl.
The documents I'm working on are from the SEC, and can be grabbed from
http://www.sec.gov/info/edgar/rel86rcxmlspec.htm, where the
"Specification Document" is a link to a Windows self-extracting
executable containing sample xml files, and the "Schema files" link
contains the schemas with which to validate them.
They have this line inside a restriction in
ownershipDocumentCommon.xsd.xml:
<xs:pattern value="[0-9A-Za-z #-]*"/>
which causes my validation to die with
Datatype error: Type:InvalidDatatypeValueException, Message:'-' is not
a valid character range; use '\-' instead.
The message is in error, because just like in perl, having a '-' at
the end of a character class means a literal '-'. I double-checked
the W3C Schema spec and I'm sure this is so.
If I escape the dash with a backslash as the error message suggests,
Xerces is happy.
