Hi Martin,

> This is exactly what I would do. If you have a lot of documents which are the same in layout, of course, you could use @rendition and <rendition>.

It's funny (but makes sense) that you said this.  I was just revising
our guidelines on this and was switching from free-@style attributes
to a more constrained set of choices via @rendition and <rendition>.

Until now we'd only used @rend with a handful of styles enumerated
externally in our ODD, but I can see the value of a declaring a TEI
document's rendition values in its teiHeader.
