Validation and schema hierarchies

[Chris Halverson <ch...@ncube.com>]

I'm getting these errors, I think its a namespace thing but I'm not sure.  I
would appreciate any help
in the offing.

[Error] :8:33: Element type "version" must be declared.
[Error] :8:33: Attribute "major" must be declared for element type
"version".
[Error] :8:33: Attribute "minor" must be declared for element type
"version".
[Error] :9:42: Element type "property" must be declared.
[Error] :9:42: Attribute "key" must be declared for element type "property".
[Error] :9:42: Attribute "value" must be declared for element type
"property".
