I think the WTP plugin works w/ HTML completion, but I've never tried it
with T5. You may need to poke around under the Preferences > General >
Content Types and Preferences > General > Editors > File Associations to
get it to recognize *.tml files as an HTML variant. You might also try
Aptan
Overall: Very good, if this stuff gets a little more fleshed out it will
be a huge help in getting started with T5. I would suggest that on the
last example in the overview (MonitorModule) you add a tiny bit of text
explaining that the contribute method is part of Tapestry IoC's
configuration
