[jats-list] Element for wrapping a group of xref elements

[Alf Eaton <eaton.alf@xxxxxxxxx>]

Is there an element in the JATS DTD that is suitable for denoting a
collection of xref elements in the body of an article?

For example, in various citation styles:

"induce co-stimulatory molecule
elevation<xref-group><xref>14</xref>,<xref>15</xref>,<xref>18</xref></xref-group>."

"induce co-stimulatory molecules elevation
<xref-group>(<xref>Gagliardi 2000</xref>; <xref>Berin
2008</xref>)</xref-group>."

"induce co-stimulatory molecule
elevation<xref-group>[<xref>14</xref>-<xref>16</xref>]</xref-group>."

If the citations were marked up in this way, then it would be possible
for the renderer to choose which style
(numeric/superscript/parenthetical) to use when rendering them.

For example, <xref-group><xref rid="ref-14">14</xref><xref
rid="ref-15">15</xref><xref rid="ref-16">16</xref></xref-group> could
be turned into a comma-separated list of numbers, a hyphenated pair of
numbers, or a semi-colon-separated list of author/year pairs, with the
appropriate punctuation.

Thanks,
Alf
