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.

I briefly wrote about it here:
