New in Quest 5.4
“list” is a sequence of any attribute type. The format is in the ASLX file:
<myattribute type="list">
<value type="string">a string value</value>
<value type="int">123</value>
</myattribute>
Usually it is better to use a stringlist (if all elements in the list will be strings) or an objectlist (if all elements in the list will be objects) instead.
There is more on lists here.
