Standard (Plug-in Neutral) Metadata Format Specification
</h1></center>
<p> The plug-in neutral "javax_imageio_1.0" format consists
of a root node named "javax_imageio_1.0" which has child
nodes "chroma", "compression", "dimension", "document", "text",
"tile", and "transparency". The format is described by the
following DTD:
