The {} notation is known as an attribute value template.  The point of it
is that anything within the {}s will be interpreted as an XPath pointing to
a node, and its value will be inserted in its place.  So, if the path:

  /XXX/YYY/ZZZ

points to the ZZZ element whose string value is "foo" then:

  href="ui.do?firstVar={/XXX/YYY/ZZZ}"

will result in the @href attribute taking the value:

  "ui.do?firstVar=foo"

It's not exactly clear from your question what your source looks like, and
what the relevant paths should be.  You do seem to be having problems with
knowing where the following:: axis should go: it's *part of* the XPath, and
so it needs to go inside the attribute value template as well.  So instead of:

  following::{XXX/YYY/ZZZ}

you want:

  {following::XXX/YYY/ZZZ}

I hope that this helps - showing some sample XML and saying what you want
to get from it is a good next step if it doesn't.

Cheers,
