First one. Now plugin.dtd is not supported extensionPoint and extensionPoints tags. This is cosmetics, the real idea here:
Will be very nice to have green plugin.xml, then we use extensions definitions. Is it posible to rewrite parser to make it as an actions parser?
Without any namespaces...
Ok, it was an suggestions, now questions.
How i can make an extension? For example, can someone post here sample of Extension?
