how to add data-cfsync=”false” attribute in sightly to ignore js in Rocketloader ?
We have implemented Rocketloader functionality on our website and we want the Rocket Loader to ignore one of the clientlibs.
https://developers.cloudflare.com/fundamentals/speed/rocket-loader/ignore-javascripts/
As mentioned in above URL, we are supposed to add data-cfasync=”false” for Rocket Loader to ignore the js, but we are not able to do so with sightly.
This is our inclusion tag
<sly data-sly-use.clientlib="/libs/granite/sightly/templates/clientlib.html"></sly>
<sly data-sly-test="${X}" data-sly-call="${clientlib.js @ categories=X}"></sly>
We tried something like this,
<sly data-sly-test="${X}" data-sly-call="${clientlib.js @ categories=X,data-cfasync=”false”}"></sly>
It did not work and gave the following exception.

Any help is appreciated. Thanks in advance.
