I'm a complete newbie, and I have tried to create styles for a number of journals: Journal of Finance, Journal of Financial Economics, and Review of Financial Studies.

Unfortunately the validation process forced me to remove the option to have papers with 4 or more authors cited with "et al" at the end.

Also, I am using Mendeley and noticed that it includes a "Working Paper" option. In my csl code, I assumed that working papers were "Reports". When selecting "Reports" in Mendeley, I could not get the words "Working paper" or the authors' institution to appear, even though everything displays correctly in the The Zotero Reference Test pane.

For example, the bibliographical citation: Brennan, Michael J, Tarun Chordia, Avanidhar Subrahmanyam, and Qing Tong, 2009, Sell-side illiquidity and the cross-section of expected stock returns.

should be

Brennan, Michael J, Tarun Chordia, Avanidhar Subrahmanyam, and Qing Tong, 2009, Sell-side illiquidity and the cross-section of expected stock returns, Working paper, UCLA and Emory.

Feel free to edit my files and resubmit to gisthub, as I'm kind of out of time for doing this.
