Note that when testing, it appears that the chrome zotero extension does not recognize tags when loading form the file system instead of over http. A simple way to get a web server running is to cd to the folder with any test docs, then "python -m SimpleHTTPServer" to start a simple web server listening on port 8000. The COINs tags were then recognized by the chrome extension.

Zotero source for parsing the context tags:

specifically, the function parseContextObject
