How can I get Intellij Community Edition to play nicely with GWT UiBinder?

First- I am not using the EAP version, which I understand has built-in support. This is not a viable option.

I am getting XML validation errors on simple things like HTML elements and ui:field="" attributes. What can i tell Idea to make it handle these things correctly? To my "Resources" settings, I already added the uibinder and clie开发者_Python百科nt.ui XSD's, as well as gwt/DTD/xhtml.ent.

GWT is not supported in the Community Edition.
