what is the xref workaround in deadline?

Hello, I was wondering if someone could explain for me or send me in the right direction in terms of what the Xref workaround is in deadline. I am not sure what this does or if I need it. Thank you.

According to the customise.ms file in your 3dsmax plugin directory:

-- WORKAROUND: XREF objects didn't pick up the xref, just rendered the proxy instead.  This maxscript
--             ensures that all the xref objects have useProxy set to the same as renderProxy to fix that.

Have a look in \your\deadline\repository\plugins\3dsmax\customise.ms
