[jats-list] @content-type on elements for bibliographic citations?

[Kevin Hawkins <kevin.s.hawkins@xxxxxxxxxxxxxxxxxx>]

As I become familiar with JATS, one thing that has struck me is that the 
content model of <element-citation> is remarkably flat.  There is no 
grouping of information within the citation -- for example, of data 
relating to an article versus information related to the journal it 
appears in, or of data related to a chapter versus information related 
to the book it appears in, or of data related to a series in which a 
book or journal issue appears.

Would anyone be willing to share a tagged examples of one or more of these:

a) A citation to a particular page or pages within a journal article 
(where you an <fpage>/<lpage> pair for the cited pages and another pair 
for the page range of the whole journal article)

b) A citation for a chapter within an anthology (where you one 
<person-group>/<collab> for the author and one <person-group>/<collab> 
for the editor of the anthology)

c) A citation for a special issue of a journal that is part of a 
monographic series (where you have a <volume> for the journal's 
numbering and another <volume> for the series numbering)

While I realize that in each case you could simply have more than one of 
the elements I list above within the <element-citation> (or 
<mixed-citation>), I'm wondering whether anyone tries to distinguish 
these with, say, @content-type, and if so, whether they have a 
controlled vocabulary for values of @content-type.  That is, how do you 
distinguish the components of such complex citations in a way that the 
citation could be processed by a machine?

Thanks,

Kevin
