+// A inlined form is used to provide a quick edition of single field for a given
+// document. Clicking on a edit button should display the form to edit the field
+// value. The form can then be submited, or just closed.
+//
+// When the form is closed we save non-submitted values in memory to avoid any
+// data loss.
+//
+// Usage:
+//
+//   +inlineForm
+//     // the content when the form is open
+//   else
+//     // the content when the form is close (optional)
+
+// We can only have one inlined form element opened at a time
