[ebxml-msg] Minor discrepancy between spec and schema

The following is an excerpt from Section 3.2.1:

The Reference element has the following 
attribute content in addition to the element content described 
above:

·          
id – an XML ID for the Reference 
element,

·          
xlink:type – this attribute defines 
the element as being an XLINK simple link. It has a fixed value of 
'simple',

·          
xlink:href – this REQUIRED attribute 
has a value that is the URI of the payload object referenced. It SHALL conform 
to the XLINK [XLINK] specification criteria for a simple 
link.

·          
xlink:role – this attribute 
identifies some resource that describes the payload object or its purpose. If 
present, then it SHALL have a value that is a valid URI in accordance with the 
[XLINK] specification,

·          
Any other namespace-qualified attribute MAY be present. A Receiving MSH MAY choose to ignore any 
foreign namespace attributes other than those defined above.

The bullet in red is inconsistent with the schema (which does 
not have the #wildcard attribute). Since the Reference element already has a 
#wildcard sub-element, and we have agreed to uniformly add #wildcard sub-element 
to most key elements to provide extensibility, I would recommend striking out 
the above bullet in red.
