Hi Denis,

I have just found the following explanation
(https://www.pragma-ade.com/general/manuals/xml-mkiv.pdf#search=xmlself):

  The macro \xmldocument expands to the current document id. There is
  also \xmlself which expands to the current node number (#1 in setups).

Now I think that I have abused \xmldocument too much, since I should
have used #1. But I’m afraid I haven’t got much different results.

I must also confess that a proper explanation would be helpful (to me in
order) to understsand when \xmldocument should not be used.
