Re: [xml-dev] referring child element of a complex element

[Michael Kay <mike@saxonica.com>]

An element cannot have both a "name" and a "ref" attribute.

Furthermore, if it has a "ref" attribute, then there must be a global element declaration with this name: you can't refer to a local element declaration (i.e one that is nested within a complexType). If you want your element declarations to be reusable in this way, make them global.
