Template for jacket, include identifiers

I am editing the template for the jacket that is stored at:

/Users/useract/Library/Preferences/calibre/resources/jacket/template.xhtml

I want to display the identifiers for the book. I attempted to use the template code:

{identifiers:select(isbn)}

But that causes the jacket creation to fail. How can I display what is in the identifiers metadata on the jacket? I would prefer to list all just as it is in the Edit metadata window, but will settle for only displaying the isbn.

What should I use and where is there a list of what metadata can be used in the jacket template?
