Re: [eclipse-dev] Eclipse Extension Point Schema Definition Change from Eclipse 3.4 to 3.5

Hi Chris,
I believe the question was the other way round:
Can we use Eclipse 3.5 (PDE) tooling to safely develop software that should run on Eclipse 3.4.
Assuming that the "appInfo" markup was being read case-insensitive by Eclipse 3.4, I believe that we don't need to worry.
And if I am not mistaken, the "appInfo" markup always just was a hint for tooling, and not relevant for the runtime.... so even
if 3.4 was case sensitive, only PDE Tooling / users of a 3.4 SDK would be affected but the runtime would work.
Yes. We know from our customers that they move slower to new versions than we do. I am aware of customers that still use 3.3 and 3.4. I wouldn´t say that appInfo is just a hint it is on the same level as JavaDoc.

I recently noticed that the Extension Point Schema Editor introduced a change in the schema definition for extension points.
It changed the element from
- element/annotation/appinfo to element/annotation/appInfo
- attribute/annotation/appinfo to attribute/annotation/appInfo
(i.e. the 'i' in appinfo changed to 'I' in appInfo)

I am wondering whether this might cause problems for users of a pre 3.5 Eclipse IDE when using exsd's from a 3.5 Eclipse IDE.

If I understand what you're asking, Eclipse never aims to be forward compatible. In reality, this means you can't take something like Eclipse 3.4 and point it to a Eclipse 3.5 target. Eclipse aims to be backwards compatible. Eclipse 3.5 should be able to deal with both of those formats.

A better forum for this discussion would be on the Eclipse PDE forums (or newsgroups)
