Is there a schema for plugin.xml files? [message #310438]

I'm wondering if a schema describing the format of the plugin.xml
files can be found somewhere? I've tried googling and searching the
eclipse news archives without much succes.

I've found references to something called "extension point schemas",
in eg.
http://www.eclipse.org/articles/Article-Plug-in-architecture /plugin_architecture.html

But I'm unsure what these "extension point schemas" are and what role
they play. It seems they are something other than what's normally
understood by XML schemas...?

Thanx!

The extension points schemas are XML schema files, used by the PDE tools
to help validate plugin.xml files.

The schema that validates a plugin.xml file is a combination of the
extension points schemas.

You can find more information in on the general plugin.xml format in
http://help.eclipse.org/help32/index.jsp?topic=/org.eclipse. platform.doc.isv/reference/misc/plugin_manifest.html

Ok, thanx. That's was a very simple format, but much is left to the
extension schemas. :-)

Now what remains to find out is if my XML editor (nxml) can be
persuaded to load a schema, and apply it to a subtree, based on an
attribute value.
