CellDesigner export: missing "type" attribute for gene, rna and antisense rna species refererences
In CellDesigner exported files, it seems the "type" attribute is missing for <celldesigner:gene>
, <celldesigner:RNA>
and <celldesigner:AntisenseRNA>
elements (species references). It should be set to "GENE", "RNA" and "ANTISENSE_RNA", respectively.
