getType

public short getType()

If {nillable} is true, then an element may also be valid if it carries the namespace qualified attribute with [local name] nil from namespace http://www.w3.org/2001/XMLSchema-instance and value true (see xsi:nil (2.6.2)) even if it has no text or element content despite a {content type} which would otherwise require content.
Specified by:
getNillable in interface XSElementDeclaration
