Sure. That's why it's better to provide a <desc/>.

Well, since <desc/> is supposed to be a longer description such as a 
tool tip or popup help (think of the difference in HTML between the 
'alt' and 'longdesc' attributes of <img/>), probably it is best to show 
nothing at all if no <desc/> is provided.

The XML schema clearly states that <option/> is allowed to contain at 
most one <value/> child (the default maxOccurs in XML schema is 1).
