Exactly. This goes together with other tips such as "define the 
structure of the output document in your stylesheets", "don't rely on 
the order of elements in the instance documents", ... which increase the 
capacity to deal with the unexpected.

It's unfortunately an exception amongst APIs, tools and languages to 
process XML documents.

This makes me think that it could make a useful extension for W3C XML 
Schema to define how to deal with the wilcard elements, something such as:

<xs:any namespace="##other" processContents="skip" 
foo:process="remove|value-of|copy-of"/>
