Avoid #-prefix in reference [message #482171]

Hi,

I've got a model defined as xsd, and since another application generates
source on base of that xsd too, I would like to replace data type
xsd:IDREF by xsd:string for my references.

This change removes resolveProxies="false" from my eStructuralFeatures in
ecore, and then my references are stored with a preceding "#" character.

So <xxx target="a" /> becomes
<xxx target="#a" />

What is the best way to avoid this "#"-character in my case?

Thanks in advance!
Peter

I suppose adding ecore:resolveProxies="false" will help... I'mnot sure
why you'd want to turn off the fact that it's an ID when really it is an
ID...

Hi Ed,

It works, thanks a lot!

Well, I wanted to know if it's possible is, that we generate sources with
Castor, and while xsd:ID results in a String, xsd:IDREF is represented as
Object.
What are the drawbacks of using string instead of xsd:IDREF?

So Castor will try to resolve IDREFS is sound like... But it seems to
me that changing the schema to change what Castor generates breaks the
schema with respect to properly constraining the actual XML, which is
normally its primary purpose.

The allowed values are not properly constrained and no other tool will
know the value is supposed to be a reference to an ID elsewhere in the
XML file...
