DSig & DOM & Databases

[Tony Coates <Tony.Coates@reuters.com>]

Does anyone have any experience with dealing with digitally signed XML documents
that are loaded into the DOM or stored in tables in a database?  I'm interested
in(i) the question of what limited manipulations you can do without invalidating
the signature, and (ii) the question of whether you need to keep textual copies
of all attributes values and element content to be able to regenerate the
original document without invalidating the signature.  All comments gratefully
received,

     Cheers,
          Tony.
