that 'attribute' tag needs to be an 'element' tag
<?xml version="1.0"?>
<info>
<element name="security-roles">
<element name="security-role">
<element name='rol' property='rolesList'/>
</element>
</element>
</info>

betwixt should handle this pretty easily. you'll need to add the name of
the adder to be used to the dot betwixt file
<?xml version="1.0"?>
<info>
<element name="security-roles">
<element name="security-role">
<element name='rol' property='rolesList' adder='setServiceRole'/>
</element>
</element>
</info>
please take a look at the documentation
(http://jakarta.apache.org/commons/betwixt) for more details.
