I am trying to define a local set with a nested local set in my own dictionary xml.

I am able to define my own local set, but would like to define a local set that includes another local set.


here is a simple example of what i want to do.

local set: corner
contains x and y integers.

local set: box
contains a,b,c,d. where all are corners.

thanks

Nested sets are specifically forbidden for MXF.

From 377m-2004, section 5.3.8:
"Note that the use of recursive group structures could prevent backwards compatibility with existing implementations and is therefore prohibited in MXF defined sets."

From 377-1-2009, section 6.3.9:
"Recursive group structures shall not be used in MXF Structural and MXF Descriptive Metadata Sets"

It may be possible to use them in non-MXF structures in an MXF file (e.g. a proprietary descriptive metadata scheme) but this has not been tested in MXFLib as it is likely to break many implementations.
