2. Submission: WPS 2.0, 14-065


1. Requirement:
clarify mechanism for referencing input/output parameter XML types

2. Implementation Specification Section number:
XML Schema

3. Criticality:

4. Comments/justifications for changes:

Trying to define WCS GetCoverage as a WPS process I cannot find how to reference 
the concrete XML input type.
The schema says:
     <attribute name="schema" type="anyURI" use="optional">
             <documentation>Web-accessible XML Schema Document that defines the 
content model of this complex resource (e.g., encoded using GML 2.2 Application 
Schema).  This reference should be included for XML encoded complex resources. 
...but I need to reference a concrete type inside this document.
In the spec itself I cannot find any hint.
In an example in 2011-05-25-WPS-Format-Definitions-for-Well-Known-Schemas.pdf 
finally I find

It should be clarified, on normative level, how to use this facility, such as:
- is the above syntax correct?
- WCS needs to reference a type (GetCoverageType), not an element.
- what if this type is defined in an .xsd file under the umbrella of wcsAll.xsd 
(in this case: wcsGetCoverage.xsd)?
