There may be something wrong in my understanding of how things are working
here but my reasons for not going down this route were
1) The script you quote is from templates.rlt and does not exist in an
individual page template project - though something similar could perhaps
be added.
2) In an individual page template project there is no project wide external
xml file, rather each separate page has its own external xml file.
3) I am seeking to implement a solution that works for both pageTemplates
and individual page template projects.
4) Even if this can be made to work for individual page template files I am
still wary of using the name property (title field in the xwd form) as the
unique identifier as I think it is already being used to meet a different
purpose that could compromise it as a unique id. A project that used
routing could easily be compromised by a late decision to change the title
of a page. Which would affect every page that had been set up to route to
it. With a separate pageID used only as the identifier for routing purposes
this issue is avoided.
Since routed pages are not yet a feature of Xerte it makes sense to get a
solution that is robust. Have I missed something in my approach? Is there
anything in the approach that I am proposing that would be detrimental to
the project?
I have performed some limited tests with this approach using my scenario
page in both pageTemplates and individual page template projects and thus
far it has worked reliably.
Kind regards
