     -- Fixed [ 810251 ] default method broken in wstools.Utility.Collection

     -- Also fixed problem with includes Collection key, and changed
        Types(Collection) class to declare a different default key instead
        of redefining several methods.

 ----------------------------------------------------------------------

Modified Files:
 	WSDLTools.py
        XMLSchema.py

    -- Fixed [ 808505 ] ZSI fails with <xs:include ... />
       Now schema include statements should be handled correctly.

    -- Also fixed a problem with relative uri handling for XMLSchema
       and SchemaReader.

 ----------------------------------------------------------------------

Modified Files:
 	WSDLTools.py -- added a line in Reader to to set WSDL.location
           for files so that imports with relative paths will work for
           file paths as well as urls.

        XMLSchema.py -- a couple Attribute fixes, and the WSDLAdapter
           wasn't passing it's parent into the XMLSchemaComponent
	   constructor which was messing up import lookups.

 ----------------------------------------------------------------------

WSDLTools.py -- just a few minor changes so the new schema class
		will be used instead of the schema tns placeholder.

		Might want to add an argument to WSDL.load method so that
                programmer can specify the placeholder or actual
		implementation.

        XMLSchema.py -- mostly new, unused original code is commented out at the bottom.

(which doesn't), so that SOAPpy can use wstools without needing ZSI
around...  which is kinda the point of generic common-code. :)

    class SOAPCallInfo:
    class ParameterInfo:
    class HeaderInfo(ParameterInfo):
    def callInfoFromWSDL(port, name):
Next step is to move what's left of wstools/ServiceProxy.py into the ZSI
module (and fix up the imports), so that wstools has *no* soap-stack-specific
code in it.
