Andrew, just out of curiosity, in what way do you use the collection()
function? I find myself using the document() function instead for
opening multiple documents (a change from 1.0 to 2.0) at once and
haven't found a reason for going for the collection() function.

I use the collection() function for generating reports or creating
indexes - generally a many-to-one transform.

For example - say you have 1000's of XML files in a directory and you
want to generate a report detailing the links in the dataset, you
would use the collection() function to access all the files, and
xsl:for-each-group to group and sort them.  You really also need
saxon:discard-document() if the total dataset size would blow your
available memory.
