# Sample Exiv2 command file for XMP tags

# --------------------------------------

# for the property, if it is not specified. The default XMP value type

# for unknown properties is a simple text value.

# A simple text property.

# The value type can be specified. Exiv2 has support for a limited number

# of specific XMP types with built-in types: The basic XmpText, array 

# types XmpAlt (alternative array), XmpBag (unordered array), XmpSeq 

# (ordered array) and language alternatives LangAlt.

# Simple text property with explicitly specified value type

# other property.

# Then set the array items. Each of them is a structure with two elements.
