alpha release of schema rev transform sheet

I'd like to release this more widely tomorrow, but consider it _very_
alpha.

Known _not_ to work with XT, uses features XT doesn't support.

Known to work with saxon, invoke as follows:

CLASSPATH=.../saxon.jar
java com.icl.saxon.StyleSheet SCHEMADOC schemaRev.xsl [copyDefaults=yes]

I recommend against using copyDefaults, especially if you use have a
<!DOCTYPE...> statement -- without it attributes with the default
values will _not_ be copied.

I urgently need to know

1) If it breaks with your input;
2) If it works with other XSLT interpreters;
3) If it takes schemas which were valid (per [1]) and produces ones
which aren't (per [2]).

I'm prepared to listen to complaints about linebreaks.

I can't do much if anything about indentation.

I've worked pretty hard to preserve comments and PIs, let me know if
anything's missing.
