string() from XPath 1.0

["Oleg A. Paraschenko" <olpa@xmlhack.ru>]

Hello,

while reading the description of the function string(), I stumbled upon
the following:

``An object of a type other than the four basic types is converted to a
string in a way that is dependent on that type.''

Probably I'm overlooking something obvious, but... what else is possible
except boolean, number, string and nodeset/node?

Thanks in advance for suggestions!
