Hi!

Precisely. One would then extract the desired topic ID from the xlink:href
attribute of the <topicRef> inside the <instanceOf>, and create the XPath
expression using that. So if there's an association whose <instanceOf>
refers to a topic with the id "foobar" in the current topic map
(xlink:href="#foobar"), the XPath expression becomes "/topicMap/topic[@id =
'foobar']".

This could also be used for trickier problems such as finding all <variant>s
whose <parameters> refer to a certain topic, as in
"//variant[parameters/topicRef/@xlink:href = '#foobar']", thereby scanning
the DOM tree recursively for matching elements. Or just scan for whatever
refers to a certain topic, as in "//topicRef[@xlink:href = 'foobar']".
