v4 Signature Clarification Needed

Could someone kindly comment on the following:

"OpenPGP states that an implementation should generate v4 signatures,
but PGP 5.x recognizes v4 signatures only on key material. This option
forces v3 signatures on data as well."

Specifically, I'm having trouble grasping the concept of 'data' versus
'key material'. Are they saying that PGP 5.x recognises a v4 signature
on a Key for instance, but will not recognise that same signature if
used to clearsign a message? Can someone provide an example of each so I
can better understand the difference between a v3 and v4 signature?

Thanks for your help.
