Re: [docbook-apps] Content model of section is not determinist

[Paul Suckling <paul.suckling@gmail.com>]

Hi Bob.

I understand what you are saying. It is useful for us to compile
individual sections of the document, so I'll keep using xi:include for
sections. However, I decided to remove the modification of the DTD
that allows xi:include in place of refentry. Instead I will use use an
ENTITY based approach for including the refentry files. I wont be able
to include the XML and DTD declarations in the refentry files, but
that doesn't matter. I am not interested in compiling refentrys as
documents in their own right. If I want to validate them individually,
I'll just have to manually specify the DTD for validation tool I am
using (via the command line or whatever mechanism it provides for
doing so).

Thanks once again for your help.

Paul
