html5 feature list anywhere? sqlite? local file access?

[Dr. Hawkins]

I am trying unsuccessfully to see what the feature list is for html5, and
what, if anything, has been omitted.

In particular, is SQLite still built in? (if not, I'd be dead in the water)

Can things be saved to local files, and read back from them?  (not much
point in creating a document that can't be saved, and need to get the
license key and other preferences).

ANd is the performance adequate for an application-sized project, as
opposed to app-sized?
