I can't help you with doing it from C++ but with MSXML 4 if you add a 
schema to a schema collection it is automatically compiled and validated 
so for instance with the following JScript code

var schemaCache = new ActiveXObject('Msxml2.XMLSchemaCache.4.0');
try {
   schemaCache.add('', 'schema.xml');
}
catch (e) {
   alert(e.message)
}

you will get a message alike

/schema[1]/element[position() = 2 and @name = '123address']
Error parsing '123address' as NCName datatype.
A name was started with an invalid character.
