Subject: [OASIS Issue Tracker] Commented: (OFFICE-3388) 5.4.1 <text:section>- Are DDE links to external data only or between sections?

    [ http://tools.oasis-open.org/issues/browse/OFFICE-3388?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=20924#action_20924 ] 

Dennis Hamilton commented on OFFICE-3388:

I agree, it is generally not possible to use DDE to access sections of the same document.  DDE accesses an application that is running outside of the consumer/producer and that is connected as a data-source using the DDE protocol.  It might be very painful/frustrating for an ODF processor to hang waiting on itself to supply the data from a DDE request to itself.

I think the wording in 5.4.1 is simply off.  I read it as saying "If sections obtain their markup via DDE, the linking information is provided in <office:dde-source> elements."

However, <text:section-source> can also find external resources, it is just done by linking rather than a Dynamic Data Exchange (DDE) arrangement.

It is certainly admissable for the link to refer to a fragment in the XML document and also to refer to a separate package file that provides some sort of markup to be used as the body of the <text:section>.  I don't know what it means for a <text:section-source> to identify a different <text:section> as its source by relative link using the <text:section>s xml:id as a fragment name.   I'd be very curious if they cross-referenced each other in that way.  

See also OFFICE-2922, OFFICE-3385, and OFFICE-3386.  OFFICE-3384 is also related.

>          Issue Type: Bug
>          Components: Text
>    Affects Versions: ODF 1.2 CD 05
>            Reporter: Patrick Durusau
>            Priority: Critical
>             Fix For: ODF 1.2 CD 06
> ODF 1.1 says for sections:  "If sections are linked via DDE, their linking information is represented by <office:dde-source> elements." Which implies that intra-document sections can be linked via DDE, whereas the current language in ODF 1.2 (5.4.1) rather explicitly uses DDE for external data sources. (Sections are wholly described in terms of external content.)
> I am not certain if any applications used DDE to link sections or not so cannot offer an opinion on the current language and existing applications. 
> I suspect the distinction was meant to be to use <text:section-source> for internal resources but that is supposition on my part. 
> That is:
> 1) External - DDE
> 2) Internal - text:section-source
