Problem with XML Schema giving Error #3070 The content model is not determinist
I have a framework which parses XML for its configuration. I have removed old 1.0 support and am now trying to parse "validators" config. The content of the validators.xsd is the same (apart from the keyword validators) as in other parts of the framework, which doesn't have any problems. I am only ever told the content model is not determinist hence am finding it hard to problem-solve. If you could point me in the right direction to getting better errors or "sanity-checks" that would be brilliant.
Here is the XSD configuration along with the matching xml notation being used. I'm not sure what to put here but I am going to give everything cited for clarity.

We exclude all the useless stuff from the ASCII range: we allow _a-zA-Z0-9 (and _a-zA-Z for the first character) from Unicode u00-u7E plus all the rest defined in Unicode.
Since we're supporting PHP 5.3+, we also allow backslashes from the second character on.
The result is that the UTF-8 representation of such a string matches the regular expression ^[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*$ (applied to the raw bytes), which is the pattern for a valid PHP "LABEL".
We start at 	, not �, because #0-#8 are invalid XMLChars.

So the problem was with the /parts/validator.xsd config containing a duplicate element which was causing the "non-determinist" error. For reference, it is my understanding that this message means you are seeing a duplicate entry or rather an entry that isn't clear on how to proceed to the next element. Hence, not determinist.
<xs:group ref="validators"
minOccurs="0" maxOccurs="unbounded" />
<xs:group ref="validators"
minOccurs="0" />
Should be:
<xs:group ref="validators"
minOccurs="0" maxOccurs="unbounded" />
