Purpose. Get/set a template field's border/edge thickness attribute (edge line width).

Description. Verified unit-conversion gap: the getter does not interpret the XFA thickness unit suffix at all. XfaWidthFromThickness scans the stored string (e.g. "1pt", "2.5mm") and simply takes the leading numeric run (0-9, ., -, +) up to the first non-numeric character, discarding everything after — it never checks whether the suffix is pt, mm, cm, or in, so a thickness authored in any non-pt unit is returned as if its bare number were already in points (e.g. "2mm" returns 2.0, not the ~5.67pt that unit would actually represent). The setter has the opposite one-sidedness: it always writes back with a hardcoded pt suffix (Format('%gpt', [Width], InvariantFormatSettings)), so Set → Get round-trips correctly (both sides agree the unit is always points), but reading a template packet authored by another XFA tool using mm/cm/in will silently misinterpret the magnitude.

Parameters.

Return value. Getter: the thickness (0 if unset, if Name doesn't resolve, or if there is no border/edge chain — all indistinguishable). Setter: 1 on success; 0 if Name doesn't resolve.
