Bob,
Use the file/export command, in the file "type" field, locate the ".xml"
value.
Press <ok>. This should unload a table in XML format. You will be given
an option to export the Schema definition (".xsd") and a style sheets
(".xsl") ("xsl" and "xls" is confusing: Excel type and style sheet type
values. Don't want to go look them up.)
