[rfc-i] xml2rfc v3 tables

[julian.reschke at gmx.de (Julian Reschke)]

Hi there.

rfc2629.xslt 
(<https://greenbytes.de/tech/webdav/rfc2629xslt/rfc2629xslt.html>) now 
supports the new xml2rfc v3 table element. It would be awesome to get 
some feedback about:

1) whether it addresses the use cases we have for tables in RFCs, and

2) what's missing with respect to styling the tables (V3 currently 
doesn't provide any control, so expect the resulting tables to be 
functional, but ugly).

In particular, it would be interesting to test the implementation with 
table-like data that in the past we had to format as fixed-width font 
artwork, because the v2 tables were too simple.

Best regards, Julian
