#1454: add part attr to schema

opened by tcatapano

to be used to indicate a div segmented on same page for layout display purposes. Since continues/continued causes the generation of text in the app, we need a workaround for divs broken up on same page for which we dont want this displayed.

attribute name = "part" values = "y|n" optional

but required if a div has an id and no head and no continued attr
