Does Kamailio not support multiple dialog elements in NOTIFY requests of the event "dialog"?

Hi,
I have a question regarding the presence + presence_dialoginfo modules
of Kamailio (tested with version 3.2.x and 3.3.x).
My SIP user agents are generating SIP PUBLISH requests for the event
"dialog" and some of these PUBLISH requests contain multiple dialog
elements in the message body. Kamailio is accepting content of these
messages and storing that information in the "presentity" table of the
corresponding DB. Taking a look into the presentity table is confirming
that both dialog elements of the PUBLISH request are stored (as body
content).
However, why does the SIP NOTIFY request, which is sent to the
"active_watchers" of this event, contain only one of these dialog
entries -- even that the modparam "force_single_dialog" is set to "0"
or
(for comparison) unset (using default value "0")? Are multiple dialog
entries not / no longer supported by the Kamailio "presence_dialoginfo"
module? The README of this module (through all versions incl. 4.1.x) is
explaining the opposite:
[...]
This module by default does body aggregation. [...] e.g. if the entity
has multiple dialogs the pua_dialoginfo will send multiple PUBLISH), the
module will parse all the received (and still valid, depending on the
Expires header in the PUBLISH request) XML documents and generate a
single XML document with multiple "dialog" elements.
[...]
Exemplary content of a PUBLISH request looks like this:

Hello,
a quick look in the code seems to use all xml nodes. Mybe you can add
some debug messages in presence_dialoginfo/notify_body.c in
agregate_xmls() functions and see what is not executing.

Hi Daniel,
thx for you hint. I´m currently working on extending DBG output on several
places / files.
In the meantime I´ve found that the presence_dialoginfo module is still able to
aggregate XML bodies. But - and that´s what I wonder about - only when the XML
bodies were "delivered" to the server in individual PUBLISH requests with
single
dialog elements only. As soon as the same information is sent to the server in
form of a single PUBLISH request with two dialog elements, only one element is
returned to the active_watchers.
Until now debug output delivered following information:
(1) the DB is storing correct content of the PUBLISH request in the presentity
table, which looks like this:
<?xml version="1.0"?>
<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info"
version="00000000004"

(2) according output of the DBG code line 'LM_DBG("KLAUS - body = %.*s \n",
STR_FMT(body));', which is inserted before 'return body' in the
'agregate_xml'
function, the return value of the agregate_xml function looks like this:
<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info"

It seems that the first dialog element of the DB entry above is returned twice
and the second dialog element is missing here! Does anybody have a hint, why the
function is returning such a malformed result??? Double entries are not
supported and that´s why the NOTIFY message is including only one dialog
element.
Thanks for any hint!
