Knowing whether a key is within a particular storage type by way of a
particular attribute: (Closed)
http://www.w3.org/2012/webcrypto/track/issues/11

Knowing where the key is stored by means other than an attribute: (Open)
http://www.w3.org/2012/webcrypto/track/issues/30

However, the premise still stands - applications should not need to be
aware of the (user-agent/implementation specific) key storage mechanisms to
successfully use this API.

This is something to be addressed at TPAC, I believe. The

Exceptions of the type I understand you to be requesting are generally
discouraged - http://darobin.github.com/api-design-cookbook/#exceptions

Correct.

Keys are not explicitly added to storage - they're implicitly added by the
act of creating them (via generate, import, or derive), and persist either
for the web context ("session") or beyond ("permanent").
