It also recognizes the ongoing schema development efforts at LandXML, aecXML and OGC, and states that "AASHTOWare task force members, contractors, and AASHTO staff will participate in these consortiums, where appropriate, and support the development and enhancement of these schemas." 6.4 Goals and Mission Statement for the TransXML Project Goals of the TransXML Project Based on the above observations, the following goals are proposed for the future TransXML Project.
