Like Ryan said, you can have an <xforms:bind constraint="..."> that
checks if less than x values are selected. This won't prevent users
from selecting more values, but if they do the control will become
invalid.

You can also have your own event handler for xforms-value-changed, and
set the value of the node to the first x values. This way when the
user selects too many values, the last value will be automatically
removed.

You can also imagine a UI with 2 lists, when the user moves items from
the first to the second by pointing to an item in the first list and
clicking on a button. When x values are selected, then you disable the
button with a bind readonly.
