<parameter role="ref" choice="opt">width</parameter>
But anyway Goba what tags (if any) do you suggest for this?
This last option seems to be fine with me.
Should go as far as adding the type here too?
<type>integer</type> <parameter role="ref" choice="opt">width</parameter>
VS
<parameter role="ref" choice"opt" type="integer">width</parameter>
Parameter has no type attribute, so only the former is possible.
