The complete fix was submitted and produced version 4615 (took me three tries to get it right, my apologies). This final fix required the complete rewriting of the ClipStringToPOlgon method in the SpatialUtilities object.
This method was originally devised for use by the MGRS grid facility (RFC 76) and this change modified the calling sequence. It does not appear that anything else in MapGuide referenced this function.

Partial fix which corrected MGRS generation in the southern hemisphere made on 28 Jan 2010 and produced revision 4554. Additional corrections required. As a result of partial fix, the ext6ernal ID changed to 1303057.
