This MIB Object MAY contain information that describes additional information defined by PacketCable specifications, including those defining PacketCable features. PacketCable specifications are expected to use this data element to obtain additional information. To specify such additional info, the following rules apply: - Each specification planning to use this MIB Object MUST specify data in the following format: '<Keyword>#<value>', # being the delimiter e.g. FEATURE_X#ABC FEATURE_Y#<value of XYZ> - This MIB Object MUST be a semi-colon separated concatenation of such '<keyword>#<value>' pairs. e.g. FEATURE_X#ABC;FEATURE_Z#DEF - Since the '#' and ';' characters are used as delimiters, they SHOULD not be specified in the keyword. If specified, any occurrence of these characters in the value field MUST be preceded by the escape character '\' (e.g. FEATURE_X#A\#C). Occurrences of '\' MUST be preceded by itself (e.g. FEATURE_X#A\\C\#). The following rules apply on the eUE: - The eUE MUST first separate all the keyword value pairs, using a '#' that is not preceded by '\' as the delimiter - The eUE MUST, For all recognized keywords, decipher the value by interpreting the data after considering the use of '\' as defined in this definition - The eUE MUST ignore and report all unrecognized keywords using PacketCable Management
