Each element in an IGDS file may have one or more attribute linkages attached to it. The IGDS reader and writer support both user data and database attribute linkages.
Note: Note, however, that the DGN V8 reader and writer do not support the interpretation of user linkages. Database linkages and MSLINKS are supported. FRAMME linkages are supported for reading.
Because an element may have more than one linkage, linkages are stored in an FME feature attribute list named igds_linkage{#}. As with other feature attribute lists, # starts at zero and increments for each successive linkage.
