CLS code to sort biblio by first author and number of authors

mgpapp · June 11, 2014

Hello,

I am almost done adapting the APA 6th style for another journal but I got stuck needing to sort the bibliography by:
1) First author
2) Number of authors
3) Year of publication

I cannot find the syntax to sort by first author or by number of authors in the CSL specification. Could someone point me to where it is?

Thank you,

Marcos

<sort>
      <key macro="author" names-min="1" names-use-first="1"/>
      <key macro="author-count"/>
      <key macro="issued-sort" sort="ascending"/>
    </sort>

with

<macro name="author-count">
    <names variable="author">
      <name form="count"/>
      <substitute>
        <names variable="editor"/>
      </substitute>
    </names>
  </macro>
