## NAME
    [Image::ExifTool::MWG] - Metadata Working Group support

## SYNOPSIS
        # enable MWG Composite tags
        use [Image::ExifTool::MWG];
        [Image::ExifTool::MWG::Load]();

        # enable MWG strict mode
        $[Image::ExifTool::MWG::strict] = 1;

        # disable MWG strict mode
        $[Image::ExifTool::MWG::strict] = 0;

## DESCRIPTION
    The MWG module contains Composite tag definitions which are designed to
    simplify implementation of the Metadata Working Group guidelines. These
    special MWG Composite tags are enabled by calling the Load() method:

        use [Image::ExifTool::MWG];
        [Image::ExifTool::MWG::Load]();

    By default, loading the MWG Composite tags enables "strict MWG
    conformance" unless previously enabled or disabled by the user. In this
    mode, ExifTool will generate a Warning instead of extracting EXIF, IPTC
    and XMP from non-standard locations. The strict mode may be disabled or
    enabled at any time by setting the MWG "strict" flag to 0 or 1. eg)

        $[Image::ExifTool::MWG::strict] = 0;

    This module also contains the MWG XMP tags which are loaded
    automatically by ExifTool as required, and are independent of the MWG
    Composite tags which must be loaded explicitly as described above.
