Ah yes, sorry. I was led astray by my particular current aminus against
scholarly editors and their publishers who still don't see what an
unnecessary obstacle to digitisation is created by line-based reference
systems in prose works. In fact, the alineation issue in the original
example is a symptom of a rather broader issue, which may still lurk even
where the exact line-break point within a <roleDesc> isn't at stake.
Leaving line-breaks aside, then, the more fundamental point is whether
there's a need to allow <roleDesc> as a sibling of castItems within a
castGroup. Or, coming back to the example, whether encoding of "Twin
brothers..." as a <trailer> really is as inappropriate (or even from Syd's
perspective, abusive) as appears at first sight.
I suspect that the impression of abusiveness comes as much from the
nomenclature as anything else, which I imagine was probably inspired (along
with <head> which can precede the <castItems>) by the div-like nature of
this structure. If we look at one of the examples in the body text of P5
(10.1.4) , we see
<head>friends of Mathias</head>
<actor>Mr Frank Hall</actor>
<actor>Mr F.W. Irish</actor>
The implication of the rend value of "braced" applied to the whole group is
that the text of the <head> should be rendered in such a way that it visibly
applies to all the contained <castItem>s. And presumably the same would hold
good about the rendering of any <trailer> that might be added after the
<castItem>s, which would take care of the general alignment problem of the
element ensemble, while remaining agnostic about specific line-breaks
within any of the text nodes. My point re nomenclature is that semantically
(though not in this case particular case syntactically) "friends of Mathias"
could be construed as a role description, in much the same way as "Twin
brothers..." could also be interpreted as such. But the Guidelines here show
that conjoined role description assigned to a <head> And if that is
legitimate (despite it not being all that much like the content of <head>s
we find elsewhere) I think there's a parallel case for assigning the "Twin
Brothers..." to a <trailer>, possibly with some mention, indeed maybe an
additional example, in the Guidelines, to indicate that it is indeed
available for such conjoint labelling, all governed by the value of "rend"
on the enclosing grouping element.
