remarked:
Travelcards on Oyster are valid on Virgin (and in theory on Scotrail,
but I don't think it saves anything) if combined with a paper ticket
from the boundary zone of the Travelcard.

Would it be correct to say that:

the Oyster Travelcard validity you mention is because the minimum
available is a "7 day season ticket"?

a Paper one-day Travelcard is not a season, but a ODTC plus a BZ ticket
*is* allowable because it's actually transformed into a 'new ticket'
viz: the return half of an outboundary Travelcard.

there's some dispute as to whether Virgin accept Oyster-based products
*at all*. [What official document confirms or denies this?]
