Nice job, Ethan. This looks really cool.
We have an Orbeon-based MODS editor, but I have found Orbeon to be a bit
tough to develop/maintain and more heavyweight than we really need. We're
considering more Xforms implementations, but I would love to find a more
lightweight Xforms application. Does anyone have any recommendations?
The only one I know of is XSLTForms (http://www.agencexml.com/xsltforms) but
I haven't messed with it yet.
