Use ECore to model XSD and IDL [message #431176]

Hello,

I'd like to use Ecore to model a DOM with specialized DOM access. The
result should be a XSD to validate content and an IDL file to define
specialized DOM access.

So for the XSD file I can use the existing ECore to XSD transformation.
To genrate the IDL files I could use one of the M2T tools (i.e. JET).

The only disadvantage I found right now is that I can't model
attributeGroups or global elements and attributes.

- Are there any other stumbling blocks to consider?
- Can I customize the ECore to XSD transformation? Where to start?

Thanks!
Kristian

You can't more model groups either, but both that an attribute groups
are really more like macros. More importantly, you can't model choice,
or other more complex types of particle structures. Global elements and
attributes can be modeled as features of the document root. In general
XSD -> Ecore -> XSD is losy so there will definitely be things you can't
represent.

I suppose.

XSDEcoreBuilder does all the work.
