The for/in/return expression is from XPath 2.0 (and is also used in
XQuery 1.0).

  http://www.w3.org/TR/xpath20/#id-flwr-expressions
  http://www.w3.org/TR/xquery/#id-flwr-expressions

The if-absent() is from the XQuery 1.0 and XPath 2.0 Functions and
Operators Working Draft, which gets pulled into XPath 2.0 (and also
XQuery 1.0).

  http://www.w3.org/TR/xquery-operators/#func-if-absent

The separator attribute on the xsl:value-of element is from XSLT 2.0.

Cheers,
