"Provides W3C XML Schema as a RELAX NG datatypes library.
|
|
NAME is a symbol giving the local name of the datatype. PARAMS is a
|
|
list of pairs (PARAM-NAME . PARAM-VALUE) where PARAM-NAME is a symbol
|
|
giving the name of the parameter and PARAM-VALUE is a string giving
|
|
its value. If NAME or PARAMS are invalid, it calls `rng-dt-error'
|
|
passing it arguments in the same style as format; the value from
|
|
`rng-dt-error' will be returned. Otherwise, it returns a list. The
|
|
first member of the list is t if any string is a legal value for the
|
|
datatype and nil otherwise. The second argument is a symbol; this
|
|
symbol will be called as a function passing it a string followed by
|
|
the remaining members of the list. The function must return an object
|
|
representing the value of the datatype that was represented by the
|
|
string, or nil if the string is not a representation of any value.
|
|
The object returned can be any convenient non-nil value, provided
|
|
that, if two strings represent the same value, the returned objects
|
|
must be equal."
