How to -- Create an OpenURL with the correct Syntax (X1)

Hi all,

I’m trying to get a list of the possible argument values for the OpenURL syntax in EndNote X1; I see several in the default preferences, but I don’t see the ones I’m looking for; specifically ISSN, DOI, etc. There are several url reference tools to leverage that would be advantageous; if I could get a full list of the possible arguments, it would be very helpful.
