[Xml-compile] Reading (hooks) according to xsi:type without xsi:type hierarchy

"any" elements and xsi:type are different things.  With <any>, you must
expect any kind of element (actually, the documentation tells you what
the options are)  Those elements are defined somewhere in some schema.

With xsi:type you can replace the type of an element with an extension
type.  It can appear anywhere in your message.  Horrible.

XML::Compile is a compiler... so: it needs to know beforehand what may
appear where.  There are a few ways how to do that, probably
   $schema->addXsiType is the easiest for you.  Find the base-type
which is used in the element definition, and then from the docs
which xsi:type can be expected there and list them.  Or try AUTO.
