(dsssl) character data and colspec

[Bob Firth <rfirth@xxxxxxxxxxx>]

I have just upgraded my linux machine from RH6.2 to RH7.2, and a dsssl
transformation that used to work now gives me an error.  Below is an sgml
document that exhibits the error.  If I run this through jade I get the
error message:

jade:xxx.sgml:11:32:E: character data is not allowed here

11:32 points to the end of the first colspec lines.

Has something changed in the docbook dtd, or possibly CALS tables?
