HexaPDFclass HexaPDF::
| Parent | HexaPDF::Stream |

Represents an XMP metadata stream.
XMP metadata streams may be attached to most PDF objects, though it only makes sense for some of them.
There is also a main XMP metadata stream for the whole document that is accessible via the /Metadata key of the document catalog. That metadata stream should contain the same values as the PDF’s info dictionary and may contain additional entries. This can be accomplished via HexaPDF::Document#metadata.
