XMI import --> invalid value according to the DTD

[incanus]

Hello,
I'm having problems when trying to XMI import a table with columns exported using DTD.

When importing i get the following message:
Error:
Code:0xc00ce017
Source = Line: 59; Character: 123
URL: file:///.../UML_EA.dtd
Error description: Attribute 'Visibility' has an invalid value according to the DTD/Schema.

it only happens with tables with columns, no problem when importing tables without any column.
if i left Use DTD unchecked i can import without any trouble, but perhaps somebody can tell the reason of the error...

best regards!
