[opencms-dev] XML-Content xsd:choice

[Thomas Göttlich]

Here's an update:

I changed the structure to define an intermediate type "OpenCmsChoice" that
instead of a sequence defines a choice of the modules.
I then added that type as an element in my test.xsd and now I can edit the
files of that type with a choice being brought up.

However, that doesn't work in Firefox (I'm using FF 6) - only in my current
IE 8 version.
