Description

The ScanAttribute processor is limited in that an exact match is required when applied for attribute value. There are many times an attribute contains a delimited list of values. It would be useful to specify a delimiter and  have the match criteria applied to each delimited value in the attribute. Two additional property descriptors need created, 'Delimiter' and 'Delimited Match Criteria'. 'Delimiter' sets the delimiter to apply to the attribute(s). 'Delimited Match Criteria' specifies how the delimited attributes should match the dictionary. If 'All Must Match' is selected, all delimited values must match a dictionary term/pattern for attribute to be matched. For 'At Least 1 Must Match' , if any one delimited value matches,then the attribute matches.
