[Exist-open] Lax cardinality on starts-with() 2nd parameter?

[Joe W. <jo...@gm...>]

Hi all,

eXist allows the 2nd parameter of fn:starts-with() to be a sequence of
1+ items.  This code returns true() with no errors in eXist 2.0 Tech
Preview's eXide:

  starts-with('my name is joe', ('a', 'm', 'z'))

But the spec states the 2nd parameter's cardinality is '?', not '+' or
'*' - see http://www.w3.org/TR/xquery-operators/#func-starts-with:

  fn:starts-with($arg1 as xs:string?, $arg2 as xs:string?) as xs:boolean
