Issue 16888: Grammar for XML Schema - XMI Canonical (canonical-xmi-ftf)
Source: Georgia Institute of Technology (Dr. Mark Kindl, mark.kindl(at)gtri.gatech.edu)
Nature: Uncategorized Issue
Severity: 
Summary: As part of our UML work for the National Information Exchange Model (NIEM) we have encountered what appear to be errors in the grammars for XML Schema in several XMI specs.  Please let us know if we have misinterpreted these issues
Resolution: Address the issues spotted: they are all generally minor syntax/consistency errors and do not affect actual XMI interchanged.
Note that for comment d4, the use of attributeGroup in rule 4e, this should be retained but encapsulated by a local xsd:complexType element.
Note: the parallel issue for the main XMI spec is 16889, which fixed some further issues.

Revised Text: All the following changes apply to section B3.2

Rule 4. ClassTypeDef.

Replace 3rd line:
"<xsd:extension base='" 4a:ClassTypeName "'")?
By:
"<xsd:extension base='" 4a:ClassTypeName "'>")?

Replace 5th line:
	( 4b:ClassContents
By:
	4b:ClassContents

Replace last line:
	"</xsd:complexType>
By:
	"</xsd:complexType>”


Rule 4e. ClassReferences:
Replace last line:
"xsd:attributeGroup ref='linkAttribs'")*
By
"<xsd:complexType>
"xsd:attributeGroup ref='linkAttribs'
</xsd:complexType>
	/>" )* 
 
Rule 4f ClassCompositions
Replace last 4 lines:
"type='" 4a:ClassTypeName "'/>" 
| (" ><xsd:complexType><xsd:choice>" 
("<ref='" 4a: ClassTypeName "'/>")*
"</xsd:choice></xsd:complexType></xsd:element>" ) )*
 

By:
( ( "type='" 4a:ClassTypeName "'/>"  )
| (" ><xsd:complexType><xsd:choice>" 
("<xsd:element ref='" 4a: ClassTypeName "'/>")*
       "</xsd:choice></xsd:complexType></xsd:element>" )  )  )*

Rule 6 StructuredDataTypeDef
Replace 3rd line:
"<xsd:extension base='" 6a:DataTypeName
	By:
"<xsd:extension base='" 6a:DataTypeName  " '>" )?

Rule 7 AssociationDef
Replace 1st  line:
"<xsd:element name='"' 7a:AssnElmtName '"'>"
	By:
"<xsd:element name='" 7a:AssnElmtName "'>"
