Missing sis-temporal module

[Cullen Rombach]

Hello,

We are trying to use Apache SIS to parse ISO 19139 metadata with a temporal
extent that looks like this:

<gmd:extent>
  <gmd:EX_Extent id="boundingExtent">
    <gmd:temporalElement>
      <gmd:EX_TemporalExtent>
        <gmd:extent>
          <gml:TimePeriod gml:id="d78cd3a2a-25a2-4216-bb87-575a0990f0f3">
            <gml:beginPosition>2001-01-01T00:00:00.000Z</gml:beginPosition>
            <gml:endPosition>2006-12-31T23:59:59.999Z</gml:endPosition>
          </gml:TimePeriod>
        </gmd:extent>
      </gmd:EX_TemporalExtent>
    </gmd:temporalElement>
  </gmd:EX_Extent>
<gmd:extent>

However, we just end up with a logged warning that says the following:

This operation requires the “sis-temporal” module.

The resulting DefaultTemporalExtent object doesn't have anything in it (
extent is null). As far as I can tell, this module does not exist in the
Apache SIS 1.0 release candidate. If this is the case, when can we expect
sis-temporal to be implemented?
