| charset |
CharacterSet
|
0..1 |
in ISO 21090 this is defined as the charset of the encapsulation of data and not of the data itself. Data that can define
its own charset (such as binary encoded XML for example) may do so. This attribute should not be interpreted as the charset
of the canonical form of the data, which will be derived from its canonical content based on the underlying media type. This
attribute is implemented as described in ISO 21090

| xml |
XML
|
0..1 |
In the instance of primary XML (or XHTML) data the ED representation is an encapsulated encoding of the XML, which may have
a different character set to the original. The actual canonical data xml may be rendered inline in the ED.xml, but might not.
If not, then the canonical representation may have to be derived to obtain the actual uncompressed xml. This is implemented
as described in ISO 21090
