 =============================================================
   BITS Version 2.0                (DAL/BTU) v2.0  (2015-12-25)
   JATS Version 1.1                (DAL/BTU) v1.1  (2015-12-15)
   JATS is a continuing maintenance NISO Standard, which
   requires voting by the ANSI and NISO memberships to be changed. 
   JATS 1.1 was approved in late 2015, and BITS modified to use
   the most recent version. No other changes to BITS were made.
4. BITS remained version "2.0" but became "v2.0 20151225"
   JATS became version "1.1" and "v1.1 20151215"
 =============================================================
   BITS Version 2.0                (DAL/BTU) v2.0  (2015-03-15)
   JATS Version 1.1                (DAL/BTU) v1.1  (2015-03-01)
   BITS was modified, based on user feedback collected in 2014 
   and January/February 2015, according to the decisions
   made by the BITS Working Group. This DTD represents current 
   BITS and an interim version of the non-normative JATS DTD 
   Suite (version 1.1), as an indication to JATS users of 
   the decisions that have been made by the JATS Standing
   Committee. 
   NISO JATS is a continuing maintenance NISO Standard, which
   requires voting by the NISO membership to be changed. This
   Committee Draft 1.1 will be sent to the NISO voting
   membership, to become (if approved) NISO JATS 1.1.
3. BOOK IDENTIFIER ATTRIBUTES - Added new attribute
   @assigning-authority to hold name of authority that
   assigned the identifier.
2. BITS became version "2.0" and   "v2.0 20150630"
   JATS became version "1.1" and "v1.1 20150301"

   NISO JATS is a continuing maintenance NISO Standard, which
   requires voting by the NISO membership to be changed. This
   Committee Draft 1.1d2 will be sent to the NISO voting
   membership, to become (if approved) NISO JATS 1.1.

<!– VOLUME IN COLLECTION –> <!– A container element for the volume metadata

for a book in a collection, for example, to
hold the <volume-number>.
Remarks: This element may repeat, with a
different language for each set of volume
data or a different usage.
Remarks: Volume information for books,
encyclopedias, and book series is not the same
kind of "volume" as the <volume> that is part
of the NISO JATS journal metadata. Large works
such as an encyclopedia may be divided into
physical, logical, or semantic volumes. A book
may be published as a monograph as well
as part of one or more collections or
monographic series. So volume information is
needed at the series (collection) level. In
addition, books of articles are published that
are similar to the <volume> in a journal
article and such volume metadata needs to be
specified at the book level.

<!– BOOK GENERIC COUNT –> <!– Generic <book-count> element to count anything

a publisher or archive may wish to count in a 
document. The @count-type attribute will name 
what is being counted (such as figures, 
tables, sections, contributors, images,
etc.) The @count attribute will state how 
many of the objects are in the document. 
Although a publisher or archive could choose 
to label all the counted objects in a document
using this element, the specific count 
elements (fig-count, equation-count,
word-count, etc.) will be retained for 
backwards compatibility, and may still be
used.
