"name" attribute is not set to property name in generated xml-mapping when using ComponentAsId.

e.g.
mapper.Class<MyClass>(map => map.ComponentAsId(id => id.Identity, cid =>
{
cid.Property(x => x.Id, x => x.Length(20));
cid.Property(x => x.EffectiveDate);
}));

Actual:
<composite-id class="EffectiveDateId, Test, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null">
<key-property name="Id" type="AnsiString" length="20" />
<key-property name="EffectiveDate" />
</composite-id>

Expected:
<composite-id name="Identity" class="EffectiveDateId, Test, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null">
<key-property name="Id" type="AnsiString" length="20" />
<key-property name="EffectiveDate" />
</composite-id>
