=item B<new>

  $xmlschema = XML::LibXML::Schema->new( location => $filename_or_url );
  $xmlschema = XML::LibXML::Schema->new( string => $xmlschemastring );

The constructor of XML::LibXML::Schema may get called with either one of two
parameters. The parameter tells the class from which source it should generate
a validation schema. It is important, that each schema only have a single
source.

The location parameter allows to parse a schema from the filesystem or a URL.

The string parameter will parse the schema from the given XML string.

Note that the constructor will die() if the schema does not meed the
constraints of the XML Schema specification.


=item B<validate>

  eval { $xmlschema->validate( $doc ); };

This function allows to validate a document against the given XML Schema. If
this function succeeds, it will return 0, otherwise it will die() and report
the errors found. Because of this validate() should be always evaluated.
