Module constructed 

Full ASN.1 framing codecs for constructed Clause-21 types whose property values are CHOICE/SEQUENCE productions — context-tagged framing per ASHRAE 135-2020 Clause 20.2.1.5/20.2.1.6.

These codecs encode to and decode from raw application-layer bytes, the same bytes carried by bacnet_types::primitives::PropertyValue::ApplicationData. Objects serve framed properties (e.g. Event_Parameters, Fault_Parameters, Recipient_List) by encoding with these functions; the flat application-tagged model in crate::primitives::encode_property_value cannot express their wire form.

Tag-form rules applied here:

• A CHOICE alternative over a SEQUENCE is an opening/closing context tag pair around the SEQUENCE’s members.
• A CHOICE alternative over a primitive base type is a context-specific primitive tag holding the raw contents (e.g. none [0] NULL).
• A context-tagged inner CHOICE is always explicitly tagged: an opening/closing pair around the alternative’s own encoding.
• Inner members declared [n] T over primitive T are context-tagged primitives; inner SEQUENCE OF / embedded SEQUENCE members are constructed opening/closing pairs holding application-tagged elements.
