Unicode normalization

There was a post on TEI-L that included a "Schematron rule (with companion xsl function) to locate and identify all non-normalized Unicode characters, and to offer a quick fix to normalize it. Code must be part of a valid Schematron file. The prefix sqf must be bound to the namespace http://www.schematron-quickfix.com/validator/process. The prefix func can be bound to any namespace."
