Re: [xml-dev] Nested Documents

Instead of pipelines, I prefer use nested XSL-T documents to interpret 
documents with nested  XHTML documents, nested SVG graphics 
(http://sourceforge.net/projects/txs)... Nested documents is a pertinent 
idea from my point of view !

Which doesn't mean months but years to wait... It's time to start !

The trouble is when we need to develop our own workarounds and add-ons 
(I'm guilty too...and I am proud of it !) : let's be pragmatic on how we 
use XML 1.0 today and let's see what should be studied to become a new 
recommendation. Is there someone to log the ideas expressed by the 
community ?
