// CLASS:    MAttributeSpec
//
// *****************************************************************************
//
// CLASS DESCRIPTION (MAttributeSpec)
//
//		Class that encapsulates component/attribute information
//		for generating selection items.
//
//      This class is used by MPxSurfaceShape::matchComponent for validating
//      attributes specified as strings and converting that specification to
//      a component object.
//
//		The attribute specification ".foo.bar[3].x" would be
//		expressed like this (using a pseudo-structure description):
//
//		MAttributeSpecArray[0..3] {
//			MAttributeSpec[0] {
//				name      = "foo"
//				dimension = 0
//			}
//			MAttributeSpec[1] {
//				name      = "bar"
//				dimension = 1
//				MAttributeIndex[0] = {
//					type      = kInteger
//					isRange   = false
//					isBounded = true
//					value     = 3
//				}
//			}
//			MAttributeSpec[2] {
//				name      = "x"
//				dimension = 0
//			}
//		}
