Editing citation styles?

[mosch]

I searched all over but couldn't find any information on the citation style I have to use. Which is pretty strange, I can't imagine nobody else having to use a similar style. I am using Office 2013 and Win7-64bit

The style I am looking for looks like this:
/1/ for in-text references
in the list of references: [1] lastname, firstnameinitial. ; <other authors the same>: Title. PlaceofPublishing: Publisher, year.

It resembles ISO 690 numerical so I'd edit that XSL file.

Can you please help me to find the relevant parts in the .XSL to:

• Change (1) to /1/ (and what is the name of the / elements in XSL?)

• Add [] brackets around the reference number in the reference list

• Remove the bold from the author names (I can't find either "bold" or "strong" or anything similar in the XSL file

• Where do I need to add semicolons or : so the author names are displayed differently?

Thanks!
