Is this related to Rolf's original question or is it a separate question?

Rolf was discussing filtering data by tag.  The above question discusses 
filtering changesets by polygon which is entirely different.  You cannot 
filter a changeset by polygon because a changeset doesn't contain enough 
information, all nodes for changed ways may not be included in the file 
therefore the location of ways may not be known.
