Section Hdr & Abstra says:

Header: Obsoletes: 7749

And, in the Abstract: 

This document obsoletes the v2 grammar described in RFC 7749.

It should say:

Header: remove the "Obsoletes" line

Abstract: 

This new version of the syntax is expected to supersede the v2 grammar
described in RFC 7749 and has started to do so.

Notes:

The norm in the IETF is that is one document obsoletes another, we treat the obsoleted document as dead and no longer to be referenced. But xml2rfc v2 is very much not obsolete and won't be obsolete until v3 is fully deployed, I-Ds are __no longer__ being prepared and passed to the submission tool in v2, and the RFC Editor stops accepting v2 files when a document is transferred to them from a Stream manager.

We should accurately describe the status of documents, not anticipate the future, especially while the most common practice _in the IETF_ is still to use the prior version and its syntax.
--VERIFIER NOTES--
An RFC can obsolete another RFC without moving the RFC to historic. This is also what is done for newer versions of certain protocols like e.g. TLS.
