RE: [xml-dev] What's wrong w/ nested elements?

Judging from the error message my guess is that the tool you are using
is trying to create a relational schema based on the document structure.
The schema it is trying to create may or may not be XSD, but it would
appear to be trying to relate element types to relations or tables with
the child elements related back to their parent elements - i.e. it is
constraining the forms of XML that it will handle.  If that is the case
then the <c> elements all appear under <b> elements and so would not be
the problem.  I do not have the tool you are using, but I would suggest
that you check how you are using the tool and what the function you are
using is supposed to do.  As Elliotte suggests, try hand authoring the
XSD and see if MSXML can handle it - I suspect that it will

Elliotte,

Thanks for your response. I can understand that this limitation (i.e.
can't nest a complex element under more than one parent) is probably in
the Microsoft tool. My example is right in front of us (thus there is no
broader issue in my application context):

<a>
    <a1>
        <b>
            <c>
            </c>
        </b> 
    </a1>
    <a2>
        <b>
            <c>
            </c>
        </b>
    </a2>
</a>

The tool is okay w/ element (c) being contained under more than one
parent. And even (b) can be present more than once under either (a1) or
(a2) but not under both (a1) and (a2)simultaneously. 

All,

Is their a way I can get the tool to behave correctly (I'm surely
missing something given how basic this is)? Or should I be using some
other editor?
