Specifies the identifier of a publication in a bibliographic reference. The attribute @pub-id-type is mandatory and states the type of identifier, authority or organization responsible for the identifier’s assignment.
Some examples of @pub-id-type are:
| Value | Description |

| doi | DOI number registered in Crossref | 
| publisher-id | Article ID in Érudit | 
| pmid | PubMed ID | 
| pcmid | PMC ID | 
| pii | Publisher identifier |

Note
- Even it is not mandatory, Érudit PS expects the presence of - @pub-id-type=doiwhen the article has a DOI number.
- Érudit PS expects to receive the DOI numbers in its raw form. It means will not be accepted any content like http://dx.doi.org/10.7202/1031001ar, but only 10.7202/1031001ar
