Hi,

Is it intentional that the GMLAS driver truncates the names of the identifiers into max 64 characters even if the output is for example GeoPackage that could handle longer names?
I know that the limit is required for PostgreSQL as documented in a comment inside the gmlasconf.xml file:
 <!-- 60 for PostgreSQL compatibility. The maximum is 64 but reserve some space so that the spatial index name can be formed -->
