[Exist-open] exist:id attribute

[Jakob <ja...@jf...>]

I think I read somewhere that exist associates one exist:id attribute with
each element node.  It appears for retrieval of a document, or when
executing a query, only the fragment root will have this attribute set.

For example, if I execute

  exist:/db/body>find document(*)/ART[@ID="MBGE.04.F96EC0E001BE3D6C"]

the root element, "ART", will have the exist:id attribute displayed, but
none of the other elements in the fragment.

Now, when executing

  exist:/db/body>find document(*)//P[. &= 'bilge']

All "P" elements will have this attribute, but again none of the children.

Now my question is whether there is a way to force this attribute to show
on all element nodes.

I want to use this on my search results page:  When the user clicks on an
entry in the hit summary, the corresponding fragment is retrieved, and I
can already indicate the exact position on the page, using <a
name="EXIST_ID"/> or similar.

Cheers,
Jakob.
