If you want the gory details I can provide them, but no, it's not, not when
all your content is optional and you already have a non-wildcard child
element from another namespace explicitly defined in the schema.

The other possible fixes are:

- wrap the other child element into this namespace (KeyInfo in this case)
- make the other child element a formal extension (not listing it explicitly
in the schema)

I hadn't proposed the latter before, but it is a possible fix.
