Re: [opendocument-users] table:table required elements

[Jean-Christophe Helary <jean.christophe.helary@traduction-libre.org>]

Regina,

Thank you so much for your detailed explanations. That is exactly what I was looking for. I'm more used to the DTD syntax so I was not sure what to make of that rnc file.

I think though that the spec reference hosted at Oasis should contain such information by using standard markers (?/+/etc.) that would be very helpful.

Regarding the file included in emacs I found that:

table-table =
  element table:table {
    table-table-attlist,
    table-title?,
    table-desc?,
    table-table-source?,
    office-dde-source?,
    table-scenario?,
    office-forms?,
    table-shapes?,
    table-columns-and-groups,
    table-rows-and-groups,
    table-named-expressions?
  }

I guess there is the way the namespaces are written that also confused me but I could not find relevant information related to table:table-column (or table-table-column ?)

Anyway, I found the compact relax ng syntax tutorial so I'll check it too so that this kind of thing does not happen again.

Now that I know what's wrong with my file, I can proceed with the xslt :) I'll probably have a few questions then, especially regarding relevant tag attributes!
