=head1 NAME

SOAP::WSDL::Generator::Template::Plugin::XSD - Template plugin for the XSD generator

=head1 METHODS

=head2 perl_name

 XSD.perl_name(element.get_name);

Converts a XML name into a valid perl name (valid for subroutines, variables
or the like).

perl_name takes a crude approach by just replacing . and - (dot and dash)
with a underscore. This may or may not be sufficient, and may or may not
provoke collisions in your XML names.
