It is always legal to omit schemaLocation.  But will that get what you
want?

The W3C XML Schema specification does not require a conforming processor to
apply any particular approach to resolving the acquisition of schema
components when <import> does not specify schemaLocation.  (Even if
schemaLocation is specified, there's lots of freedom).

I suggest that you need to look at the schema processors you intend to use
to see how they handle this.  For example, Apache's Xerces processors
provide an API so that you can supply an EntityResolver which allows your
own code to recognize any well-known namespace URIs you care about and
indicate to the processor where to get a schema document that corresponds
to it.

Subject:    import w/o schemaLocation





When you import a schema for a well-known namespace (http://www.w3.
org/2001/XMLSchema), is it legal to omit the schemaLocation attribute?  If
the parser is "schema-aware", is it supposed to automatically handle the
import as if it had been explicitely specified?
