Fails,
Environment MGOS 4 Beta 2 & latest MapGuide-Rest RC6 (package download) is currently have this issue that Gordon mentioned, but the same issue doesn't apply to XML or HTML generation.
For example /rest/session/1d86c8fe-995a-11ef-8000-7c4c58745c63_en_MTI3LjAuMC4x0AFC0AFB0AFA/Property.Selection/features.geojson/QBParcels?transformto=WGS84.PseudoMercator&pagesize=1&page=1&mappedonly=1&displayproperties=1 Fails,
but... /rest/session/1d86c8fe-995a-11ef-8000-7c4c58745c63_en_MTI3LjAuMC4x0AFC0AFB0AFA/Property.Selection/features.geojson/QBParcels?transformto=WGS84.PseudoMercator&mappedonly=1&displayproperties=1
