It looks like an unintended omission to me. I would say "If the *expected*
database version is an empty string", which is ambiguous as well, but it is
about the "expected version" of course.
I think that if someone opens a database without expecting a particular
version and the database already exists the openDatabase() call should

openDatabase() is called with a database name and an expected version
If the database has a version, and it is different than the expected
version, openDatabase() fails. This makes sense. But...
"Otherwise, if the database version is the empty string, or if the
database doesn't yet exist, or if the database exists and the version
provided to the openDatabase() method is the same as the current
version associated with the database, then the method must return a
1 of these 3 situations doesn't make sense. A database without a
version should not be considered valid if the caller to openDatabase()
expects a version.
This seems silly as two callers, one expecting "versionFoo" of a
database and the other expecting "versionBar" will both be allowed
access to a versionless database.
That seems like an instant recipe for failure for at least versionFoo
or versionBar, possibly both.
I think that if someone opens a database with an expected version and
the database already exists but has an empty version string, the
openDatabase() call should fail.
