Not as far as I know.

The original red <?XML!> logo (as in the top LH corner of the pop-out menu 
in the FAQ at https://xml.silmaril.ie/) was, I think, done by Tim Bray (but 
my memory may be faulty on that point), and there were metal lapel buttons 
given out at one stage by some generous person. The logo uses the Futura font.

How about a matching <?XSLT!> in a different colour? I think there is a lot 
to be said for a logotype which can be represented in plaintext as well as 
typographically.
