  This would mean that for all the element nodes in the tree a new structure
is allocated. Sorry, too heavy.

  Sounds like a good solution. but not for the entity nodes. For the element
integrated from the external entity. Normal attributes in the XML sense.
This would just fail to work if people used external parsed entities to
include top text nodes (which can't hold attributes).
  Sounds actually a lot like xml:base

  This would be done only when running under the XSLT debugger and performances
are not from my point of view a problem there.

  Adding entities nodes will not work with XPath. Adding an attribute
value at the insertion point would need a single callback adding API.
