=head1 NAME

Pod::WSDL::Utils - Utilities and constants for Pod::WSDL (internal use only)

=head1 DESCRIPTION

This module is used internally by Pod::WSDL. It is unlikely that you have to interact directly with it. If that is the case, take a look at the code, it is rather simple.

=head1 METHODS

=head2 getTypeDescr

Returns a type description for type attributes in the wsdl document

=head1 EXTERNAL DEPENDENCIES

  [none]

=head1 EXAMPLES
