<dtml-let items="_.string.split(string_with_1_or_more_words)">
<dtml-let numitems="_.len(items) > 1">
<dtml-if "numitems > 1">
we have &dtml-numitems; items
<dtml-else>
we have one item
</dtml-if></dtml-let></dtml-let>

Or you can access sequence-size as _['sequence-size']:
<dtml-if "_.int(_['sequence-size']) > 1">
