From XPath, SPARQL uses these functions:
  definition of the type <numeric>

  fn:not(xs:boolean)
  op:boolean-less-than(boolean, boolean), greater-than

  op:numeric-unary-plus(numeric), minus
  op:numeric-equal(numeric, numeric)
  op:numeric-less-than(numeric, numeric), greater-than
  op:numeric-multiply(numeric, numeric), divide, add, subtract

  fn:compare(xs:string, xs:string); including the regexp language

  op:dateTime-equal(xs:dateTime, xs:dateTime)
  op:dateTime-less-than(xs:dateTime, xs:dateTime), greater-than

  constructor functions for boolean, float decimal, double, integer,
  dateTime and string.

From XQuery, we use <type error>, Expression Processing, 
and lean a bit on Effective Boolean Value 

None of those appear to have changed either in semantics or in the
text needed to describe their invocation. Based on this, I believe
that DAWG has no dependencies on this update to XQuery and XPath
Full Text.

Good luck.
