Re: including a schema document multiple times

The spec is clear about multiple inclusion of the same document is OK. See 
sections 4.2.1.

"Note: The above is carefully worded so that multiple <include>ing of the 
same schema document will not constitute a violation of clause 2 of Schema 
Properties Correct (§3.16.6), but applications are allowed, indeed 
encouraged, to avoid <include>ing the same schema document more than once 
to forestall the necessity of establishing identity component by 
component."

It's less clear about circular inclusion, but it's generally believed that 
it's also allowed.

including a schema document multiple times







Hello,

is it problematic to include a schema document multiple times via 
different 
paths?  For example, I might have a schema document which includes schema 
documents A, B, and C which in turn include a schema document providing 
basic 
definitions.

What about circular inclusion?

Best wishes,
Wolfgang
