# FdoSpatialContextList
[XML Schemas]

This schema governs the output of MgContextSpatialReader::ToXml(). What follows is a representation of the element hierarchy in FdospatialContextList-1.0.0.xsd. Frequency of element occurrence is indicated by adding a quantifier symbol (* for 0 or more, + for 1 or more, ? for 0 or 1 and nothing for 1) to the end of the element identifier.
