The user guide is still in progress - but what's published on the 
website so far (particularly the decriptions of page/component 
properties) is very relevant to v3.0.

Whenever you have <property-specifications...> defined, Tapestry will extend the page and provide 
implmentations for these properties. So that's when you would define your page class as abstract.
