Class name with 2 sequence

[iversonmania]

<id name="countryid" column="country_id" >
<generator class="sequence">
<param name="sequence">country_s</param>
</generator>
</id>

I have that, but i also have another column in that same table countries..
which is not primary key, unlike countryid..pluis its number..and works as sequence as well

<property name="typenum" column="type_num"/>
