RE: [xml] Schema validation fails with global definitions

[Israel Ganor <ganor softlink com>]

Hi Daniel,

These are complete samples of a schema and XML file. 
Validating this XML file using xmlSchemaValidateDoc() (Windows libxml 2.6.7)
shows the error 
"Element USER content check failure".

Thanks in advance
