[opencms-dev] Complex articles in XML with OC6

[lists at rueth.info]

Hi!

In OpenCms5 I've been using my own xml article mechanism (which is in
the OpenCms Module Sandbox for download). The principle of the OpenCms6
XML article management is a bit similar, but of course much more
advanced, and I am looking forward to using it and throwing my own
stuff away.

Still, when trying to build an article using the OpenCms6 mechanism, I
seem to encounter certain limits. This may be due to my unexperience
with this mechanism, but maybe also due to real limits of this
mechanism. For example, I need articles consisting of several sections,
each with an optional title. Each of those sections can enclose text,
images and links. Have a look at my old xsd file, which I paste below.

- Is it possible to get a similar article structure using the OpenCms6
article mechanism?
- If yes, how??? Examples would be highly appreciated!
- A valid OpenCms6 xsd file seems not to allow complex types nested
inside the "singular" (without the s at the end) complex type
definition, neither by defining them "anonymously" inside this type
definition, nor by adding additional "named" complex types (like I did
before, see below) and referening them by name. Is this correct?

Please help me get going, or stop me from getting too frustrated...

Regards
Ulrich
