<p style="margin: 10px 0 0 0">I'd assumed that each PrincipalType would be represented by a different attribute definition. If any Principal could render more than one value then that too would be a different definition. This seems to me to be a simpler configuration to get your mind around that a DataConnector with a series of descriptions for each attribute.</p>
<p style="margin: 10px 0 0 0">Apropos the DataConnector/Attribute Defintion thing:</p>
<p style="margin: 10px 0 0 0">I'm hampered of course by not knowing the deployment. Of course if the only need for the attribute is to feed into the logic of an attribute release policy we are fine, but I'm assuming here that the issue is that we actually want the attribute to be released.</p>
<p style="margin: 10px 0 0 0">This of course means adding Encoders to the Connector-y thing... Which in turn makes me realize one of the reasons why we have the namespace oddness - the DataConnectors do not necessarily know the names of the attributes it is going to produce.</p>
<p style="margin: 10px 0 0 0">So we'd need something like</p>
<p style="margin: 10px 0 0 0"><DataConnector ....><br /> <Attribute InputName= OutputName=...><br /> <Encoder .... ><br /> <Encoder .... ><br /> <Attribute ...><br /> <Encoder .... ><br /> <Encoder .... ></p>
<p style="margin: 10px 0 0 0">Which isn't a million miles away from just having separate Attribute Definition for each Attribute (although in code terms there may be advantages - like only have one connection to a database per resolution)</p>
<p style="margin: 10px 0 0 0">Either way the "Thing" needs garnished so it's a choice between adding stuff to a DataConnector and having a new type. </p>
<p style="margin: 10px 0 0 0">Adding to the DataConnector might make for problems with code compatibility: there may be Interfaces and we might need to add AbstractMethods, whilst this is not insurmountable, it makes for ugly code.</p>
<p style="margin: 10px 0 0 0">Further there might be problems with customer comprehension, so perhaps something entirely different is in order - then the question is whether we make it a NamedAttributeDataConnector or a MultiAttributeDefinition. Based on no real information (like I say I don't have a feel for the deployments) I'd sort of favour the DataConnector, since I'd assume that you would be interested in having all the same DataConnectors (LDAP, RDBMS, Static and so on).</p>
<p style="margin: 10px 0 0 0">More discussion needed....</p>
