> Algebricks has a few internal functions used as generic representations of the languages functions for optimizing the query plan. I noticed that we support boolean(value-eq()), but are missing support for "=" in joins. A map needs to be made to the XQuery general conditional functions to and from Algebricks functions. The process must be able to convert boolean(value-eq()) and "=" to and from algebricks-eq.
