Schematron validation based on the contents of another file!

I have added two more examples to Schematron tutorial at:
http://zvon.vscht.cz/HTMLonly/SchematronTutorial/General/contents.html

I have just realized, that Schematron engines  based on XSLT can use
XSLT function: document() to perform this type of validation.

Example 18
A paragraph in XML 2 can only start with words specified in XML 1 (file
source1.xml)

Example 17
XML 1 (file source1.xml) contains a list of authors. These authors are
referred to in XML 2. The Schematron checks if for each referred author
in XML 2 exists an entry in XML 1.
