While creating some tests for assertions I've come across some assertions 
that I think specify the same requirement. I'll point these out here and 
suggest that a single assertion be defined for each restriction as 
multiple assertions may lead to problems interpreting the spec and will 
lead to ambiguity wrt the assertion that should be flagged as an error for 
a WSDL document that does not comply with the spec.

1. Import-0001
However, any WSDL 2.0 document that contains component definitions that 
refer by QName to WSDL 2.0 components that belong to a different namespace 
MUST contain a wsdl:import element information item for that namespace 
(see 4.2 Importing Descriptions ). 

Import-0070
As with XML schema, any WSDL 2.0 document that references a foreign 
component MUST have a wsdl:import element information item for the 
associated foreign namespace (but which does not necessarily provide a 
location attribute information item that identifies the WSDL 2.0 document 
in which the referenced component is defined). 


2. QName-0002
Furthermore, all QName references, whether to the same or to different 
namespaces MUST resolve to components (see 2.17 QName resolution ). 

QName-resolution-1219000
A Description component MUST NOT have such broken references. 

Types-1300000
Every QName reference MUST resolve (see 2.17 QName resolution). 


3. Import-0003
Imported components have different target namespace values from the WSDL 
2.0 document that is importing them. 

Import-0071
This value MUST NOT match the actual value of targetNamespace attribute 
information item in the enclosing WSDL 2.0 document. 


4. Schema-0016 
A WSDL 2.0 document MUST NOT refer to XML Schema components in a given 
namespace unless an xs:import or xs:schema element information item for 
that namespace is present or the namespace is the XML Schema namespace, 
http://www.w3.org/2001/XMLSchema, which contains built-in types as defined 
in XML Schema Part 2: Datatypes Second Edition [XML Schema: Datatypes]. 

Types-1300001
When resolving QNames references for schema definitions, the namespace 
MUST be imported by the referring WSDL 2.0 document.
