Re: [PHP-XML-DEV] Re: DOMDocument::schemaValidate() - group nodes inside choice nodes

Hi

It's not PHPs task to validate your schema, the library used behind, 
libxml2, is doing that. So if something doesn't validate, but it should, 
it's not our "fault". libxml2 has has still no feature complete XSD 
Support (AFAIK), but they made some big progress latetly. It's therefore 
a good idea to use one of the latest libxml2 releases and check, if they 
maybe fixed that issue.

I didn't look at your XSD and check, if it's valid at all. I'm no XSD 
expert, but I assume, you checked it already with another validator ;)
