<include schemaLocation="">
The <include> declaration combines XML Schemas that are designed for the same targetNamespace(or no targetNamespace).
Within the <include> declaration there is no namespace attribute.
The <include> declaration can be used only on documents with the same targetNamespace, or no targetNamespace.
When a schema validator encounters an <include> declaration, it treats the global declarations from the included XML Schema as
if they had been declared in the XML Schema that contains the <include> declaration.
