Image::ExifTool::TagInfoXML \- Read/write tag information XML database
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module is used to generate an \s-1XML\s0 database from all ExifTool tag
information.  The \s-1XML\s0 database may then be edited and used to re-generate
the language modules (Image::ExifTool::Lang::*).
.SH "METHODS"

Flags (if selected and available) are formatted as a comma-separated list of
the following possible values:  Avoid, Binary, List, Mandatory, Permanent,
Protected, Unknown and Unsafe.  See the
tag name documentation and
lib/Image/ExifTool/README for a description of these flags.  For \s-1XMP\s0 List
tags, the list type (Alt, Bag or Seq) is also output as a flag if
applicable.
