Hi Matthew,

[Sorry for the delay.  Been on travel. I don't seem to be subscribed to
this list group, so I don't know if there were any responses to your
post. (How do I subscribe?)]

Here are my comments:

Hmm, I don't quite see this. Both the <include> element as well as the
<import> element reference a (schema) file.  For example:

<include schemaLocation="URI to a schema file"/>

<import namespace="namespace of schema"
        schemaLocation="URI to a schema file"/>

With both elements a file is referenced.  Thus, if you change the name
of a schema file it will impact all schemas that reference it,
regardless of whether it is being referenced using <include> or
<import>.  Thus, I don't see how using <include> minimizes file
dependencies any more than <import> does.  Perhaps I am not
understanding your point?  /Roger
