[rfc-i] draft-iab-xml2rfc-03, "2.54 <table>"

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

<https://greenbytes.de/tech/webdav/draft-iab-xml2rfc-03.html#rfc.section.2.54>:

>1. One optional <name> element (Section 2.32)
>2. Optional <iref> elements (Section 2.27)
>3. One optional <thead> element (Section 2.59)
>4. One or more <tbody> elements (Section 2.55)
>5. One optional <tfoot> element (Section 2.57)

a) I'm not totally convinced anybody will use <tfoot>.

b) When running conversion tests, I discovered test cases that verify 
that texttables that only contain column titles work; converting them to 
v3 format yields a <table> element with <thead> but no <tbody> child 
element. This would be valid HTML5; why do we disallow it?
