RE: Is schemaLocation Required When Importing Inline Schemas?

Thank you for your comment - we tracked this as a Last Call comment
LC116 [1].  The Working Group agreed to incorporate the suggest text at
[2] (with some small modifications).

 

If we don't hear otherwise within two weeks, we will assume this
satisfies your concern.

Subject: Is schemaLocation Required When Importing Inline Schemas?

 


The spec currently says that when you refer to inline schemas within the
same document you need to provide a schemaLocation attribute with a
suitable fragid in the xs:import statement: 

Inside an embedded XML schema, the xs:import and xs:include element
information items MAY be used to refer to other XML schemas embedded in
the same WSDL description, provided that an appropriate value is
specified for their schemaLocation attribute information items, such as
a fragment identifier (see [XML Schema: Structures
<file:///d:\workspaces\Corona%20V6.0\W3C\wsdl20\wsdl20.html#XMLSchemaP1>
] 4.3.1). The semantics of such element information items are governed
solely by the XML Schema specification [XML Schema: Structures
<file:///d:\workspaces\Corona%20V6.0\W3C\wsdl20\wsdl20.html#XMLSchemaP1>
]. 

I thought we said the fragid was unnecessary since the WSDL processor
knows where to find the schemas. 

On the other hand, there was a very long thread [1] about how to refer
to an inline schema from another WSDL document. The thread ended
inconclusively with an action item [2] that doesn't seem to exist. The
conclusion seems to have been that you didn't need the schemaLocation,
but the behavioir was dependent on the processor. 

Can we please tighten this up? I just created some Primer text that may
not be correct. 

I propose that we require a WSDL processor to know how to locate any
inline schemas it encouters while processing a document so that the
schemaLocations are not required. 

"If schemaLocation is not present then a WSDL processor MUST attempt to
locate the schema among the inline schemas it has encountered while
processing the WSDL document."
