PVPython: how to get strings from filter in python?

Hello dear ParaView developers!

I want to have a python function which returns the list of strings representing the internal parameters of my custom filter

I know how to get individual numbers - for those IntVectorProperty is used, and the label of this xml somehow (how, btw?) converts to python wrappings.

But how to get the list of strings? I have totally failed to find any info about it

Help me please

Thank you
