package XCAFDoc 

    ---Purpose: Definition of general structure of DECAF document
    --          and tools to work with it
    --
    --          The document is composed of sections, each section
    --          storing its own kind of data and managing by corresponding
    --          tool
    --          Some properties can be attached directly to shapes. These properties are:
    --          * Name (the standard definition from OCAF) - class TDataStd_Name
    --          * Centroid (for the validation of transfer) - class XCAFDoc_Centroid
    --          * Volume (for the validation of transfer) - class XCAFDoc_Volume
    --          * Area (for the validation of transfer) - class XCafDoc_Area
    --          Management of these attributes is realized by OCAF. For getting
    --          the attributes attached to a label the method class
    --          TDF_Label::FindAttribute() should be used.

	---Purpose: Defines types of color assignments
	--          Color of shape is defined following way
    --          in dependance with type of color.
    --          If type of color is XCAFDoc_ColorGen - then this color 
    --          defines default color for surfaces and curves.
    --          If for shape color with types XCAFDoc_ColorSurf or XCAFDoc_ColorCurv is specified
    --          then such color overrides generic color.
