Validation using a schema

[Dantzler, DeWayne C]

Hello, 

I trying for the first time to validate an XML document with a schema,
but I'm not sure of the results from the parser. I'm currently using
Xerces C++ 2.8.0 DOM Parser. What is the correct syntax to specify a
schema? If the schema and xml file are in the same directory can I just
use the filename of the schema or do I have to specify a full pathname?
If the schema is not in the same directory or location then what is the
correct syntax? Here's what I've done.

Code snippet:
==========================================================
//perform the necessary DOM Parser init and setup 
... omitting all the gory details

//setup the Entity Resolver to redirect the parser to use the external
Schema 
_XmlDOMParser->setEntityResolver(resolver);

//Turn on the necessary features to allow validation by an external
Schema 
_XmlDOMParser->setValidationScheme(_XmlDOMParser->Val_Always);

//enable schema processing
_XmlDOMParser->setDoSchema(true);

//specify schema to use where scheme syntax is the filename i.e bcme.xsd
_XmlDOMParser->setExternalSchemaLocation((const char* const)schema);
_XmlDOMParser->loadGrammar(schema, Grammar::SchemaGrammarType, true);


//ignore DTD's
_XmlDOMParser->setSkipDTDValidation(false);

//attempt to parse the xml
_XmlDOMParser->parse(xmlDoc2Parse);
==============================================================

Results: Lots of Parser Errors but several of the elments are defined in
the schema. See schema and xml below
