Is there any API to fetch the internal names of all the soft attributes available on a type say "wt.part.WTPart"?

I need to fetch the internal names of all the IBAs available on a type (ex: wt.part.WTPart). Is there any API already available? If not, can some one help with the approach/code to get this?

I am using 10.2 M010.

Thanks in advance.
