<!-- From jpub3-html.xsl v3.0 to jats-html.xsl v1.0:
  
Calls to 'normalize-space($node)' where $node is not a string are
expressed as 'normalize-space(string($node)) in order to provide
type safety in some XSLT 2.0 processors.

Support for certain elements in NLM Blue v2.3 is added to provide
backward compatibility:
  floats-wrap (same as floats-group)
  chem-struct-wrapper (same as chem-struct-wrap)
  custom-meta-wrap (same as custom-meta-group)
  floats-wrap (same as floats-group)
  gloss-group (same as glossary)
  citation
  contract-num
  contract-sponsor
  grant-num
  grant-sponsor

Support is added for looser structures for title-group elements
in 2.3 (title, trans-title, trans-subtitle etc.) Same for 2.3
tagging of permissions info (copyright-statement, copyright-year,
license) and funding/contract info (contract-num, contract-sponsor,
grant-num, grant-sponsor).

Elements newly permitted in JATS journal-meta
(contrib-group, aff, aff-alternatives) are supported.

New elements in NISO JATS v1.0 are supported:
  aff-alternatives
  citation-alternatives
  collab-alternatives
  trans-title-group (with @xml:lang)
  contrib-id
  count>
  issn-l
  nested-kwd

Added support for @pub-id-type='arXiv'

Named anchor logic extended to support "alternatives" wrappers
for aff, contrib, citation etc.

Footer text is emended, with name of transformation (stylesheet
or pipeline) parameterized.

  <!-- ============================================================= -->
  <!--  MODE 'label-text'
	      Generates label text for elements and their cross-references -->
  <!-- ============================================================= -->
  <!--  This mode is to support auto-numbering and generating of
        labels for certain elements by the stylesheet.
  
        The logic is as follows: for any such element type, if a
        'label' element is ever present, it is expected always to be 
        present; automatic numbering is not performed on any elements
        of that type. For example, the presence of a 'label' element 
        in any 'fig' is taken to indicate that all figs should likewise
        be labeled, and any 'fig' without a label is supposed to be 
        unlabelled (and unnumbered). But if no 'fig' elements have 
        'label' children, labels with numbers are generated for all 
        figs in display.
        
        This logic applies to:
          app, boxed-text, chem-struct-wrap, disp-formula, fig, fn, 
          note, ref, statement, table-wrap.
        
        There is one exception in the case of fn elements, where
        the checking for labels (or for @symbol attributes in the
        case of this element) is performed only within its parent
        fn-group, or in the scope of all fn elements not in an
        fn-group, for fn elements appearing outside fn-group.
        
        In all cases, this logic can be altered simply by overwriting 
        templates in "label" mode for any of these elements.
        
        For other elements, a label is simply displayed if present,
        and auto-numbering is never performed.
        These elements include:
          (label appearing in line) aff, corresp, chem-struct, 
          element-citation, mixed-citation
          
          (label appearing as a block) abstract, ack, app-group, 
          author-notes, back, bio, def-list, disp-formula-group, 
          disp-quote, fn-group, glossary, graphic, kwd-group, 
          list, list-item, media, notes, ref-list, sec, 
          supplementary-material, table-wrap-group, 
          trans-abstract, verse-group -->
