Sure we have.  This is a classic case where escape to script makes sense.
This particular formatting operation is not in the 90%-common case (or even
99% case), and so should not result in complicating the declarative parts of
XSL.  A graceful escape to script for purposes like this should support this
kind of customized (in this case string-level) formatting.

Something like this:
<define-script>
  function myTextTrimmingFunction(string) {
    // arbitrary string manipulation goes here
    return result;
  }
</define-script>

<rule>
  <target-element type="p">

  <paragraph>
    <eval>myTextTrimmingFunction(this.text)</eval>
  </paragraph>
</rule>
