Index of all topics in a set of Mallard pages

Hi,

Is there any facility in Mallard for creating an alphabetical index of
topics, even ones that are not linked to on the main 'index.page'
guide page?

What I tried is to create a section on the main index.page:

<section id="full-index">
  <title>Index</title>
</section>

and then a separate guide page, full-index.page, which every topic
page links to using something like:

<link type="guide" xref="full-index"/>

This works fairly well, except for three things:
- You have to manually add a link on every topic page.
- When viewing with Yelp, where each page normally shows its hierarchy
at the top, (e.g. Foo Guide ->  Foo Topic) it now also shows a second
entry (Foo Guide ->  Index ->  Index of all help topics).
- There is a see-also link on the bottom of every topic page that
points to the index.

Is there perhaps some sort of style="no-see-also" attribute possible
that one can use to suppress these see-also and hierarchical links to
the index?
