C++ implementation of XML schema XSD 1.1?

Question

Is there any existing C++ implementation of the XML Schema XSD 1.1?

I found xerces-c++-3.1.1, but it only implements XSD 1.0. The java counterpart of this project does implement XSD 1.1.

I am notably looking for a way to implement the 'assert' functionality.

Answer 1

The only released XSD 1.1 processors I am aware of are Xerces-J and Saxon-EE, which are both Java-based (though Saxon-EE is also released on .NET).

(EDIT, SIX YEARS LATER)

There is also an implementation from Altova.
