[SAC] Should parser resolve Unicode quoting?

Given this stylesheet:

.footnote\2e reference { vertical-align: super }

what is the selector's AttributeCondition.getValue() method expected to
return,

    "footnote\2e reference"
 or 
    "footnote.reference"?

Flute 1.3 returns the former, i.e. it seems not to unquote the value. The
SAC API specification, unfortunately, makes no precise mention as to what
to expect.

General question: Is Flute 1.3 to be considered a reference
implementation of SAC and therefore reasonably complete, bugless and
stable? If not, can you recommend a different implementation that can be
said to be a reference implementation?
