registering new properties for existing classes

Hi All,

I'm writing my own vfd and I'd like to register some new file access
properties with the existing class.

All the examples testing properties in tgenprop.c appear to also create
a new class of property list before calling H5Pregister.

So, is adding new 'permanent' properties to existing pl classes
supported?

  You won't be able to modify the default property lists that the library creates, but you should be able to add your own properties to a file access property list (in your application) and then check for those properties in your VFD.
