I was thinking of this kind of feature just today !

But I'd like to be able to insert code at additional locations :
- before startDocument(), identical to your <xsp:init-page> and after
endDocument(). This is to set up things before anything gets generated,
and allows also, if an error occurs during this setup, the error-handler
to generate a clean page. After endDocument(), cleanup can be performed,
e.g. releasing components.

- before startElement() and after endElement() of the root element, to
allow global namespace mappings to be defined.

I was thinking to use the existing <xsp:logic> outside of the page
element feature, but with additional attributes on it :
- <xsp:logic before="document">, <xsp:logic after="document">
- <xsp:logic before="root-element">, <xsp:logic after="root-element">

Ovidiu and others, what do you think of this ?

And can we easily alter the XSP syntax that is also used by AxKit (BTW,
the xsp-dev list is _very_ quiet) ?
