This function returns 1 (True) if the attribute lines for the element identified by oid are displayed in the Document Map window. It returns 0, otherwise.

If newval is specified, it changes the state of the attribute display for oid. If 0, the attribute lines are removed (collapsed). If non-zero, the attribute lines are displayed (if the element has any non-default attributes).

Note, the effect of this function is visible in the Document Map and Column view only.
