And that snapshot is a portable document. But just the snapshot; not the
larger pool.

My PDF bank statement is a portable document, but my data in my bank's
database is not -- though if they gave me a mysqldump file of the data, it
would be portable.

Customers can get a document they can carry with them that can be updated,
and that might be "portable" by some definitions (eg. you can put it on a
USB stick in your pocket). But it's not portable by the defintion we are
using here. We are specifically defining "portable" to mean "all of the
essential material is accessible offline". This is a hugely necessary
concept in publishing; I'd give examples from our business, but I think we
all have reams of examples of this in our pocket.

Much as "document" has myriad meanings all over tech and indeed all over
the W3C, this is a case where "portable" needs to have different meanings.

'Portable" to a user might mean "I can stick it in a USB stick in my
pocket." To the PDF team it might mean "shows the same document on a smart
phone as on a web tv as on a TRS-80 model III." (Forgive me if I'm wrong;
that's my understanding of the "portable" in PDF, but you're the expert!)
And to Dpub, I believe the meaning we're looking for is "if you give it to
astronaut Samantha Cristoforetti and she puts it on her e-reader, she can
enjoy a good novel while aboard the Soyuz spacecraft taking her to the ISS."
