gml:AbstractFeature 

This abstract element serves as the head of a substitution group which may contain any elements whose content model is derived from gml:AbstractFeatureType.  This may be used as a variable in the construction of content models.  
gml:AbstractFeature may be thought of as "anything that is a GML feature" and may be used to define variables or templates in which the value of a GML property is "any feature". This occurs in particular in a GML feature collection where the feature member properties contain one or multiple copies of gml:AbstractFeature respectively.
