--- Comment #2 from Mark Watson <watsonm@netflix.com> ---
I suggest the following modifications:

Key Session:

Old: "A Key Session, or simply Session, represents the lifetime of the
license(s)/key(s) it contains and associates all messages related to them."

New: "A Key Session, or simple Session, provides a context for message exchange
with the CDM as a result of which a key or key(s) are made available to be
CDM."

Key

Old: "A key is associated with the session used to provide it to the CDM. (The
same key may be present in multiple sessions.) Such keys may only be provided
to the CDM via an update() call. (They may later be loaded by loadSession() as
part of the stored session data.)"

New: "A key is associated with the session used to make it available to the
CDM. The same key may be present in multiple sessions."

License:

Old: "A license is a key system-specific message that includes one or more
decryption key(s) - each associated with a key ID - and potentially other
information about key usage."

New: "A license is key system-specific state information that includes one or
more key(s) - each associated with a key ID - and potentially other information
about key usage."

[Note that 'key' in our document always and only refers to content decryption
keys. That doesn't mean other keys can't exist, they're just not described in
our specification.]
