Return Value

Type: System.String

Returns the passed-in string if all the characters in the argument are valid public id characters.

No other values than the passed in argument should be returned. The characters valid for public id do not vary between XML editions, so no XmlVersion overload is required.

See XML 1.0 spec (fourth edition) production [13] PublidChar for details on the allowed characters

If the parameter is null, an ArgumentNullException will be thrown. If any of the characters are not valid public id characters, an XmlException is thrown with information about the first invalid character encountered.
