Adding a qualifier attribute to a given node using MDHT

Adding a qualifier attribute to a given node using MDHT

I am trying to add a qualifier attribute to a given node.
PN name = DatatypesFactory.eINSTANCE.createPN();
name.addGiven("Phillip");
name.addFamily("Partridge");
Which should produce:
<name>
<given>Phillip</given>
<family>Partridge</family>
</name>
I also want to add initials:
<name>
<given>Phillip</given>
<given qualifier='IN'>P.J.</given>
<family>Partridge</family>
</name>
but none of the PN functions allow me to specify the enum
EntityNamePartQualifier as a parameter.
