Latest WSDL XML

Regarding [1]:
I am having trouble reading this document.

Two questions:
1) Is it legal to have the following in the file:
<!DOCTYPE xs:schema PUBLIC '-//W3C//DTD XMLSCHEMA 200102//EN'
                           'http://www.w3.org/2001/XMLSchema.dtd' [

<!ENTITY % entities SYSTEM 'entities.dtd' >

%entities;
]>

It seems that two tools have trouble with this construct.

Second question:
The schema declaration:
<xs:schema xmlns:xs='http://www.w3.org/2001/XMLSchema'
           targetNamespace='&wsdl-ns;'
           xmlns:wsdl='&wsdl-ns;'
           elementFormDefault='qualified' >

Uses '&WSDL-ns;'.  This looks like some sort of parameterized expansion.
Can some one clue me in to how this works?

thanks in advance
sgg
