Sorry, my mistake.
My shortcode looks like this:
[easyreview title="MyTitle" cat1title="MyCategory" cat1detail="This is the <a href='http://en.wikipedia.org/wiki/Detail' target='_blank'>detail</a>" cat1rating="5" tablecss="easyReviewWrapper"]
It would be nice if it could look like this (escape sequence for quotation marks):
[easyreview title="MyTitle" cat1title="MyCategory" cat1detail="This is the <a href=\"http://en.wikipedia.org/wiki/Detail\" target=\"_blank\">detail</a>" cat1rating="5" tablecss="easyReviewWrapper"]
As the missing escape sequences for shortcode is not the fault of the Easy Review Builder plugin I hoped to find a suitable workaround here.
