Re: [docbook-apps] Questions about DocBook 5.x

[Ellyn Larson <elarson@portalyx.com>]

Hello Jirka,

Many thanks for your input. I've been working on what you suggested and 
doing the customization in RELAX NG.

Can you tell me what tool(s)  in the DocBook repository I should be 
using to convert the RELAX NG schema into a DTD and W3C XML Schema?

Many thanks,
Ellyn Larson
