The DtNavigationFeatureStringParser parses the object attributes found in the strings used by streamed object marker names. The string is a ':' separated list; The fields provide the attribute/value pairs in the form ATTRIBUTE=VALUE. Value comes directly from an S-57 data (or a shape file extracted from S-57). These values may themselves be comma-separated lists of values.

Example: The following could be a the marker name in the .earth file: "COLOUR=" + [COLOUR] + ":TOPSHP=" + [TOPSHP] + ":CATSPM=" + [CATSPM] When the marker is streamed in, osgEarth replaces [COLOUR] with the attribute values in the S-57 or shape file, say 3, 1, and 8 respectively. Then the resulting marker string is "COLOUR=3:TOPSHP=1:CATSPM=8". These are broken down into attribute/value pairs that can then be accessed by the DtNavigationFeatureBuilder. Some attributes with multiple numbers may be concatenated (or only choose the first item)
