Purpose. Get/set a template field's border/edge presence attribute (XFA's visible/hidden/inactive/invisible edge-display toggle).

Description. Same <field> → <border> → <edge> chain as the color function above, reading/writing the edge element's presence attribute directly (no value translation). Defaults to 'visible' if the field has a border/edge chain but no explicit presence attribute — matching the XFA spec default — but returns empty if the field itself, or its border/edge chain, doesn't exist at all (these two "no value" cases are otherwise indistinguishable from the API alone).

Parameters.

Return value. Getter: the presence string ('visible' default, or empty if unresolvable). Setter: 1 on success (creates the border/edge chain if missing); 0 if Name doesn't resolve.
