 1. With 2.2 RC2, the standard template uses the fusion/lib/def directory
 while the other templates use the template/def directory.

 The problem relates to the single file version using lib/defs, while the
 uncombined version uses template/defs

 2. MapGuide provides a WKT projection, but it's not being passed to
 Proj4js for parsing.

 i.e. the map I'm currently working with has this projection in the map
 definition

 <CoordinateSystem>PROJCS["MGA-55",GEOGCS["LL-
 GDA94",DATUM["GDA94",SPHEROID["GRS1980",6378137.000,298.25722210]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Transverse_Mercator"],PARAMETER["false_easting",500000.000],PARAMETER["false_northing",10000000.000],PARAMETER["scale_factor",0.999600000000],PARAMETER["central_meridian",147.00000000000000],PARAMETER["latitude_of_origin",0.00000000000000],UNIT["Meter",1.00000000000000]]</CoordinateSystem>

 looking at the proj4js-combined.js file around line 486, I see the
 following code

  //check to see if this is a WKT string
      if ((srsCode.indexOf('GEOGCS') >= 0) ||
          (srsCode.indexOf('GEOCCS') >= 0) ||
          (srsCode.indexOf('PROJCS') >= 0) ||
          (srsCode.indexOf('LOCAL_CS') >= 0)) {
            this.parseWKT(srsCode);
            this.datum = new Proj4js.datum(this);
            this.loadProjCode(this.projName);
            return;
      }

 The SRS being passed is only the EPSG:28355 string, as opposed
 to the definition from the map

 hacking around, If I change the line in LoadMap.php line 114

    $mapObj->wkt = $srs;
    $mapObj->epsg = $epsgCode;

 to

    $mapObj->wkt = $srs;
    $mapObj->epsg = $srs;

 Result: no external projection requests as proj4js parsing
 of PROJCS is triggered.
