Grammatical erratum in XPath spec

Section 4.2 says,

The string-length returns the number of characters in the string (see 
[3.6 Strings]). If the argument is omitted, it defaults to the context 
node converted to a string, in other words the string-value of the 
context node.

That should be

The string-length function returns the number of characters in the 
string (see [3.6 Strings]). If the argument is omitted, it defaults to 
the context node converted to a string, in other words the string-value 
of the context node.

i.e. add the word "function"
