I am using AAF SDK to create an AAF file. I need to add mobattributeslist property into composition mob. However, I was trying to use RegisterOptionalPropertyDef() function to register this new property. Unfortunately  it's failed. I would like to know what is the right way to create mobattributeslist property(type def is tagged value variable array) in composition mob.

Any idea welcomed.
