/* Function callable by interface designers. Returns index in parameter
|
|
list of a specified parameter for an element (i.e., 1 for first parameter
|
|
specified in the DTD, 2 for second, etc.). First parameter, elt, is
|
|
the name of the element. Second parameter is the name of the parameter
|
|
or NULL. Third parameter is used only if second parameter is NULL. In
|
|
the latter case, function returns first keyword parameter, if any, for
|
|
which the specified value is a legal value and otherwise first
|
|
Returns 0 if elt is not a valid element name, if param is specified
|
|
but is not a valid parameter name, or if param is NULL and value is
|
|
not a valid value of any of elt's parameters. */
