Code	Description

Where the hydroNodeCategory has not been identified, this attribute is set to null and a nilReason of inapplicable is given. This will indicate where an attribute of the watercourse changes which requires a watercourseLink to split, for example, watercourseName. In the Esri shapefile, these are given the attribute value of pseudo.
