Section 3.5 says:

Use of program names for the identification of encoding formats 
is not desirable and is discouraged for future encodings. Their 
use here is representative of historical practice, not good 
design. For compatibility with previous implementations of HTTP, 
applications SHOULD consider "x-gzip" and "x-compress" to be 
equivalent to "gzip" and "compress" respectively.

It should say:

Use of program names for the identification of encoding formats 
is not desirable and is discouraged for future encodings. Their 
use here is representative of historical practice, not good 
design. For compatibility with future implementations of HTTP, 
applications SHOULD consider "x-gzip" and "x-compress" to be 
equivalent to "gzip" and "compress" respectively.

Notes:

"For compatibility with previous implementations of HTTP",
here, 'previous' should be replaced by 'future'.

Comment by Peter Saint-Andre:

This erratum is incorrect -- the text is clearly about
backward compatibility, not forward compatibility. The
original poster can comment in the HTTPBIS WG about this
matter since draft-ietf-httpbis-p1-messaging has very
similar text.
