John F. Schlesinger found an error in my suggested stylesheet - this was for
generating a DTD with a highly repetitive structure -

Looks like I misremembered where the disable-output-escaping attribute can
go.  XT liked it anyway, though.  Just move the attribute to the
xsl:value-of statements that create the declarations and everything should
be OK.  Sorry to confuse you.
