Further experiments on that point:

Right now, it's working exactly as you describe if I write:
<action
when="/form/action = 'save' and not(/form/document//[EMAIL
PROTECTED]:valid = 'false' and not(ancestor-or-self::[EMAIL PROTECTED]:relevant
= 'false'])]) "
action="save-new-document.xpl">
<result page="apiculteur">
<xu:update select="/form/document-id">
<xu:value-of
select="translate(normalize-space(document('oxf:instance')/form/document/rdf:RDF/bk:beekeeper/bk:name),
' AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz�������������
�����������������������������������������������',
'+aabbccddeeffgghhiijjkkllmmnnooppqqrrssttuuvvwwxxyyzzaaaaaaaaaaaa�
�cceeeeeeeeiiiiiiii��nnoooooooooo��uuuuuuuuyy��')"
/>
</xu:update>
<xu:remove select="/form/*[not(self::document-id)]"/>
</result>
</action>
The issue with this solution is that I need to duplicate the logic that
computes an ID from the document.
Right now, this is *only* more difficult to maintain (I need to update
this logic at two locations).
And, in the future, I might have to extend this algorithm (for instance
to check for duplicates in the database) and it might even become
impossible to implement with pure XPath.
This ID being already computed in the action, is there a way to pass its
value from the action to the update statement?
Thanks;
Eric
