Code in t/lib/TestRunner.pm intentionally causes the
test t/02yaml.t to skip testing of XML::LibXML
::SAX::Parser when the latter is registered on the
build machine as one of the SAX parsers (for example,
through ParserDetails.ini). This is because
t/02yaml.pl assumes that for each registered parser
module X, it can explicitly create a new instance by
invoking X->new(). However, for
XML::LibXML::SAX::Parser there is no "new()" method.
One creates a new instance by calling
XML::LibXML::SAX->new(). So there is no need to skip
testing of the Validator with XML::LibXML::SAX::Parser,
just instantiate it as XML::LibXML::SAX->new().
Run the attached patch as 'patch -p1 <
TestRunner.pm.patch' from the parent directory of the
XML-Validator-Schema development root dir.
