ores.trading.trade_envelope

One row per trade whose document stated an envelope, keyed to the trade.

The envelope is the block a document wraps around a trade. It names a counterparty, a netting set, a list of portfolios and a list of further fields the document states in its own vocabulary. The schema states all four as optional and the last as open content.

The trade row already carries a counterparty and a netting set, but those are the trade's own attributes and the trade states them unconditionally. The envelope is the document's statement and may omit either. A row here holds what the document said, so a reader distinguishes an omitted member from a stated one.

A scalar member needs no flag of its own: a null column says the document omitted it and an empty string says the document stated it empty. The two list members are not like that, because an omitted list and a stated empty list both write no child row. Each therefore carries a flag on this row that says the document stated it.
