Re: DOCBOOK-APPS: Re: Q's:Adding affiliation to authorgroup template

[Martin Stemplinger <mstemplinger at gmx dot de>]

I had only looked at my customization layer and not tried that myself. Sorry
for that. The error was (as Bob pointed out) that affiliation is a child of
author.
So you need to include both author and affiliation. Additionally you need to
provide a custom version of affiliation for the titlepage which why included
it in the customization layer.

I think it is fine to use the attribute 'predicate' since:
Each element may have a single attribute: predicate. The value of this
attribute is used as a predicate for the expression that matches the element
on which it occurs. (From Norm's documentation)

You may take a look at the template and the customization layer enclosed.
They work for me.

Hope this helps
Martin
