According to https://unifysolutions.jira.com/wiki/display/IDBXT306/Multi-value+Distinguished+Name+generator+transformation, the multivalue DN generator introduces a temporary field of MultivaluePart to an entity in order to run the DN generator across every value in a multivalue field. As this is not a field in the adapter schema, the field is not displayed in the dropdown when configuring the transformation, or in the DN generator for the transformation.
As such, a special type of DN generator should be introduced that is able to take a multivalue field in a component generator and produce the multivalue DN field accordingly. The transformation would no longer need to use a temporary field as a result. This would need to be done in such a manner that existing DN generators function correctly, and that it was only in the context of this transformation that the DN generator behaves this way (as multivalue fields in DNs can be used externally and simply print the multivalue as a string).
