Description:
According to http://www.w3.org/TR/xpath-functions/#func-concat, fn:concat is supposed to concatenate the values of all parameters passed to it. However, when using it in ExtractValue, only the first two parameters are passed.

How to repeat:
SELECT EXTRACTVALUE("<a><b>d</b><c>o</c><d>g</d></a>", "concat(/a/b,/a/c,/a/d)");

^It *should* return "dog", but instead it returns "do".
