The XML Reports for Corridors sometimes contain values in metric units and need conversions within the reports. The units are specified in the reports, so creating and applying a conversion factor is certainly do-able. A number of the older reports would call out the units and even do some conversions.
I've noticed a number of items in the Corridor Reports are not searching for the correct attributes or nodes. They may report no Parametric Constraints, Point Controls or Secondary alignments when there are some of these in the reported upon corridor.
