When {{cs1}} and {{cs2}} templates contain {{para|biorxiv}}, a test is done to see if the [[bioRxiv]] identifier has the proper form.  There are two valid forms, each beginning with bioRxiv's doi directory indicator and registrant code (10.1101) and followed by:
: six numeric characters without punctuation or spaces:
::{{para|biorxiv|10.1101/######}}
::: <code>######</code> – 6-digit bioRxiv identifier
: ymd format date prefix followed by six numeric characters without punctuation or spaces followed by optional version:
:: {{para|biorxiv|10.1101/yyyy.mm.dd.######v#}} where:
::: <code>yyyy.mm.dd.</code> – represents a date no earlier than 11 December 2019 (<code>2019.12.11.</code>) and no later than tomorrow's date; date must be a valid date
::: <code>######</code> – 6-digit bioRxiv identifier
::: <code>v#</code> – optional version indicator

A common error is to include the bioRxiv ''URL'' (<code>{{red|<nowiki>https://dx.doi.org/</nowiki>}}10.1101/######}}</code>).

To resolve this error, ensure that the {{para|biorxiv}} value is correct.
