[xmlroff] Implement DocBook extension functions for xsltproc?

[Tony Graham]

>From http://xmlroff.org/ticket/83:

http://www.sagehill.net/docbookxsl/InstallingAProcessor.html describes
some DocBook extension functions that are presently only implemented for
Saxon and Xalan.

Is it necessary to implement them for xsltproc so xmlroff can use them?

Regards,


Tony.
(who rashly said on the DocBook-apps list that it would be simple to
implement them.)
