[Muscle] custom tags for IFDGetCapabilities

[Jens Miltner]

Regarding IFDGetCapabilities: Is there a range of tags reserved for application specific needs?
What I'm looking for is a way for an application to find out whether a given reader supports intrinsic PIN input (i.e. has built-in keypad and has a safe PIN input mode). Since PC/SC doesn't seem to account for this, I figured one way would be to define a new tag to be passed to IFDGetCapabilities (and hope that as many ifdhandlers as possible will eventually implement support for this tag).

Is there a standard procedure for 'applying' for new capability tags?

Or, better yet, is there another way to find out whether a reader has support for PIN input?
