I am getting a bit perplexed by numeric constructors in: 



[Issue 149: Either the constructor functions should allow dynamic
   expressions or the syntax should be changed so that they do not appear 
to   be functions. ]

What is meant by dynamic expressions? Does it mean that the argument must 
be "12" but something like (xf:short(xf:concat("1","2")) will not be 
permitted ? 


notation looks a bit perplexing:
xf:short(string $srcval) => integer
xf:byte(string $srcval) => integer

should not it be rather:
xf:short(string $srcval) => short
xf:byte(string $srcval) => byte

Standard says:

If the argument string passed to a constructor results in an error
(for example, if it conatains a letter other than "E" or "e" or a string 
other than the special values named above), the constructor returns the 
error value as defined in [XQuery 1.0 and XPath 2.0 Data Model].


is very vague. What will be the return value
or will it be a fatal error?
