allow ALIAS attribute to show attribute value from latest iteration of part and documents

[ayap]

The current behavior when we have an ALIAS attribute point to a part/document IBA attribute, it would show multiple values from all the iterations of the object.

It would be beneficial to have syntax to show the value from the latest iteration.

In general it should be possible to restrict alias navigation by constants / literals. Notation for conditions could e.g. be in square brackets (similar to XPath).

Examples for proposed solution:

• Navigate only to WTParts where latestIteration=1

• Navigate only to WTParts where lifeCycleState=INWORK

• Navigate only to WTParts where latestIteration=1 AND lifeCycleState=INWORK
