No, you're not.  XSLT handles *sorting* fairly well, but it doesn't
handle grouping at all well, and won't until XSLT 2.0.  There are
techniques for doing grouping that work OK, but they're not
particularly easy to get to grips with - see for more details.

It's 'wrong' if you change the *underlying* XML to suit the
presentation. However, you could have a preprocessing stylesheet that
takes the XML data and sorts it, before the data is then passed on to
the presentational stylesheet. This isn't 'wrong' at all - in fact
it's a good approach to the problem, better than performing the
complex transformation in a single step.
