PAP declaration

Declare each PAP article using a custom-meta-group element.

/article-meta/custom-meta-group

In each PAP article, capture a custom-meta-group with a meta-name value article-lifecycle and meta-value PAP.

Remove this custom-meta-group from the article once it is published in an issue.

<custom-meta-group> 
<custom-meta> 
  <meta-name>article-lifecycle</meta-name>
  <meta-value>PAP</meta-value>
 </custom-meta>
</custom-meta-group>
