Yes, fn:path (not fn:node)!
the following works
<fas><nom>this is an example</nom></fas>/nom/fn:path(.)
with the useful result
Q{http://www.w3.org/2005/xpath-functions}root()/Q{}nom[1]
but the following does not (because tokenize() does not return a node)
<fas><nom>this is an example</nom></fas>/tokenize(nom, " ")/fn:path(.)
what I was looking for is a function returning something like
<t path="Q{http://www.w3.org/2005/xpath-functions}root()/Q{}nom[1]" start="0"
end="3">this</t>
<t path="Q{http://www.w3.org/2005/xpath-functions}root()/Q{}nom[1]" start="5"
end="6">is</t>
<t path="Q{http://www.w3.org/2005/xpath-functions}root()/Q{}nom[1]" start="8"
end="9">an</t>
<t path="Q{http://www.w3.org/2005/xpath-functions}root()/Q{}nom[1]" start="11"
end="17">example</t>
