I like the suggestion. However, the function should probably be called
emitStringValue in order to make it clear what the exact semantics is.

Title:
Item API needs operator<<
Status in Zorba - The XQuery Processor:
New
Bug description:
To emit the string value of an Item to an ostream, you currently have
to use getStringValue() or getStringValue2(). This is inefficient
since a string that is otherwise not needed needs to be created.
Instead, there should be a global operator<< defined:
std::ostream& operator<<( std::ostream&, store::Item const& );
Its implementation could simply call a new protected, pure virtual
member function for Item:
virtual void emit( std::ostream& ) const = 0;
