Hi Folks,

An XML Schema simpleType can have a base type. And that base type may have a base type. And so on.  Further, the types may be in different schema files and in different namespaces.

Determining the constraints on a simpleType in this "dependency chain" can be challenging.

I created an algorithm for merging all the constraints in the dependency chain and rendering a single, standalone simpleType:

Comments welcome.
