Subject: Jing & Trang errors when processing RNC grammar



Hello, 

I am considering using RelaxNG for describing the structure of XML
configuration files used in a enterprise software system, because its syntax
seems far more intutive than Schemas.

I have developed a grammar by reading the RelaxNG tutorial, but when I
attempt to validate it using Jing (within OxygenXML) I get an brief error
message I cannot understand: E "oneOrMore" contains "group" contains
"attribute" 

When I use the inbuilt Trang tool, I can successfully convert the compact
grammar to XML form, but a conversion on to XML Schema results in a message
like "Choice between attributes and children cannot be presented;
approximating", but no schema object is produced.

There doesn't seem to be any reference or further explanation for parsing
errors. I have spent several hours on this and will have to abandon the use
of RelaxNG unless I can obtain a speedy resolution.

My grammar is shown below, including a leading * indicating the line the
validator fails on. Note that it relates to the only case of recursion in
the grammar- a ConfigGroup can contain nested ConfigGroups within it.  Is
anyone able to offer some explanation as to what these problems mean? Any
general advice on how to "debug" a RelexNG grammar would also be
appreciated.
