table whitout lines xml export/import

Hi,

we have in a document a table witout lines.

we use a atribut cold "ohneLineatur" in the edd & RW-ruls and a table format whitout lines in the template.

when exporting in to xml, the atribut "ohneLineatur" is there.

importing it back into framemaker, the table has lines.

where are they coming from?

thanks for any hint.

best regards

beat
