Major Description
If a wsdl file imports an xsd and you try to specify a package name using -p, then the following error is given.
"-p option cannot be used when wsdl contains mutiple schemas"
While this is correct, it would be more useful to say
"-p option cannot be used when wsdl contains mutiple schemas, unless a namespace to package mapping is specified,
for example -p http://blah.com=com.blah -p http://foo.com=com.foo"
