Hello,
I have a question regarding the planned DocBook 4.2 support in the next
version of XXE.
Before you provided the downloadable DocBook 4.2 files, I had already
included my own version in my local installation. I have used a
different approach though, and I would like to discuss this here on the
list.
The patch you provide makes a distinction between 4.1.2 and 4.2, these
are two totally different configurations. As far as I see currently,
this makes customization a bit harder than necessary, because I would
think that a customization I apply is not specific to the DocBook
version I use.
My question is: Is it really necessary (there might be some internal
reasons for this) to separate DocBook 4.1.2 and DocBook 4.2 like you do
in your patch?
I used the following approach to have DocBook 4.2 support in XXE:
- moved the existing config/docbook/dtd to config/docbook/dtd/4.1.2
- put DocBook 4.2 in config/docbook/dtd/4.2
- adjusted entity paths
- adjusted catalog.xml to the new paths
Anything else stayed the same. I am quite sure that I have missed
something, but at least this setup worked for me...
... after having written this, I had a better look at the docbook42
directory you provide, and it seems that the 4.2 configuration includes
large parts of the docbook 4.1.2 configuration anyway. It seems to me a
bit confusing to have two "toplevel" configurations (namely docbook and
docbook42) when this could also be achieved with one configuration.
I realize that you are working on this anyway, so what we got with the
patch might not be what is in the next version, but anyway, these are
just my two cents, so please feel free to comment.
Cheers
Bernd
