Hi Werner,

just a few questions on the contents of the datatype row:

- I assume types like PersonNameType are defined as XML Schema data types?
Could you add a reference to the definition or paste in the type? I know the
table will get large, but the information would be very valuable IMO.
- Is there a restriction on the value of Unique ID, e.g. that it has to
follow xml:id? Again a reference would be great.
- Is "string" just a Unicode string? In general: Is there a restriction on
the character encoding of MPEG-7? XML requires not more than utf-8 and
utf-16, but others are possible.
- What is the difference between UniqueIdentifier and Unique ID?
- In "string and qualifier", what is the pattern (reg.ex.) to describe the
- are values like float, non-negative float or non-negative integer
identical to
