When I try to create an XSD for this XML using Microsoft Development

the following error:

Failed to Create a schema for this data file because:
Although this XML document is well formed, it contains structure that 
Data View cannot display.
The same table (b) cannot be the child table in two nested relations.

Wondering why the containment relationship shown above is not valid 
for an XSD? And what can
I do to workaround this problem (I can't afford to name mangle (b) 
everywhere it appears).

There's nothing here the W3C XML Schema Language can't handle. The 
problem is with the Microsoft tool, not with XML. Try hand authoring 
a schema and see if it accepts that, though given the error message I 
suspect the problem may not be quite what you think it is. It sounds 
like there might be broader issues in your application context that 
prohibit this normally allowed structure.
