At the moment, AE only shows attributes, when they have a value or, when the value differs from the default value.
We'd like to have the possibility, to show all attributes, even if they have no value or if they have the default-value.
This should be configured separately for the docmap and the editwindow.
Perhaps with a new setting: showallattrsindocmap and showallattrsineditwindow
The competitors oXygen and XMetaL has a kind of function like that, where all attributes of an element are permanently present in a window, showing all attributes: those with no values, with the default value (from Schema or DTD) and those with user-edited values.
In really complex documents, this would help a great deal.
