Specify how the Namespace Summary is sorted.
The parameter has the following meaning:
true),
the namespaces will be sorted alphabetically by their URIs (ignoring letter case).
false),
the namespaces won't be sorted anyhow. The ordering of namespaces
will be determined by what WSDL/XSD files have been specified initially
and how they reference (e.g. import) other WSDL/XSD files.
