I fear that there is no database with a special flag indicating 
that the exon/intron organization is known.  In GenBank, one 
can look for features "intron" or "exon" in the features 
table.  But if these features are absent, this does not 
mean that the genomic organization is unknown-- it might be 
that the gene has no introns, or it has introns and exons 
implicit in the "join" statement, but not explicit in the 
features table.  

It would be very useful for databases to have obligatory 
designations like "complete/partial" and "genomic/other".
