| 解説 | This ‘superclass’ provides attributes that
can be used to provide normalized values of temporal information.
By default, the attributes from the att.duration.w3c class are provided. If the
module for names & dates is loaded, this class also provides
attributes from the att.duration.iso
class. In general, the possible values of attributes restricted to
the W3C datatypes form a subset of those values available via the
ISO 8601 standard. However, the greater expressiveness of the ISO
datatypes is rarely needed, and there exists much greater software
support for the W3C datatypes. |
