New blog post: "How the new Form Builder Appearance Selector Works"

All,

The following blog post we wrote last week describes a new feature in
Orbeon Forms, but this use of appearances combined with custom controls
bound declaratively via CSS selectors shows great flexibility and has
implications beyond XForms:

I think that the generalized notion of "appearance" is one of the great
contributions of XForms. Frameworks like Google's Polymer, based on Web
components, could benefit from embracing this notion.

Enjoy,
