xmlSchemaIsValid() just says if a previous validation succeeded or
not.

First create a W3C XML Schema parser context with:
 - e.g. xmlSchemaNewParserCtxt

then parse & compile the schema with:
 - xmlSchemaParse

then create a validation context for the compiled schema with:
 - xmlSchemaNewValidCtxt

then validate your in-memory document with:
 - xmlSchemaValidateStream 
   (Have a look at the code of xmlSchemaValidateFile(), which
    uses xmlSchemaValidateStream)

OR, first parse your in-memory document and create a node-tree with:
 - xmlReadMemory
and then validate the node-tree with:
 - xmlSchemaValidateDoc
