What about document oriented editing? Forms and word processor kind of functionality?

I'm researching browser development frameworks and languages to develop an XML editor. Editing should work more like Google Docs than CodeMirror, and with rudimentary form support (think key-value metadata, not complex forms).

So far I have settled on using contenteditable, but structural editing of XML in document oriented fashion is still an open question. One user action can result in many XML tree changes, like pushing enter twice inside a paragraph should split it in two (and thus close and create any number of tags). Also, there is no schema to describe XML document's editing workflow. Your post on IDE as a value gave me insight for a possible implementation.

Also, big thank you for LT. I'm enjoying using it immensely.
