Nit: how to determine fingerprint equality?

[foolip]

The match an installed app steps have:

4.5.1. If installedApp’s fingerprints does not contain fingerprint, return null.

In one pedantic reading, the one list can never contain the fingerprints of the others, because they won't be the same instances of the Fingerprint concept:

A fingerprint has the following two properties: type and value. Each of these are strings, but their syntax and semantics are platform-defined.

Is the comparison also platform-defined, or simply comparing the string values of both properties? No trimming of whitespace or other normalization before comparing?
