I would like to use the APA CV style for a report which sorts the entries by descending dates. However, I experience that at the end of the outputted bibliography, all the conference papers (paper-conference) appear and the list is therefore not sorted overall by dates. Is this some special APA rule or is this an error?

The reason for the behavior is the following macro in the CSL file:

<macro name="date-sort-date">
<choose>
<if type="article-magazine article-newspaper broadcast interview pamphlet personal_communication post post-weblog speech treaty webpage" match="any">
<date variable="issued" form="numeric"/>
</if>
<else-if type="paper-conference">
<!-- Capture 'speech' stored as 'paper-conference' -->
<choose>
<if variable="collection-editor editor editorial-director issue page volume" match="none">
<date variable="issued" form="numeric"/>
</if>
</choose>
</else-if>
<else>
<date variable="issued" form="numeric"/>
</else>
</choose>
</macro>

For every case the same line <date variable="issued" form="numeric"/> is performed. However, all conference papers with an editor (or any other of the mentioned variables) are excluded and therefore no value is given for these cases. Can we fix this and what would the correct case distinction be here?
