When specifiying a url for a document using a document's universal id (aka unid or @text(@documentuniqueid) or universalid ) the view name does not have to be correct.

Consider the url for this document:

 The 501e...5df bit is the view name and if you use the view name it works as well.

You can actually put anything in there and it will work.

Best practice is to put in the view name in the text format, as then the user can go back to the view and find other documents etc which could be useful if the link fails etc.

I have also seen $DefaultView used, and of course to shorten a URL you could just use a single letter etc.

I presume it is an optimisation by the programmer: if the unid is valid and the user has access then just open the document, there is no reason to open or check the view first.

Could be considered a security risk, ie keyword documents or user's registration documents could be accessed but if you want to hide a document, just put proper security on it using reader's fields!
