Copying attributes from chained line to parent line

There may be instances when certain attributes need to be copied from the chained line to the parent line. This will be done based on the template ChainedOrderUpwardPropagationTemplate of the chained order document type.

If multiple children exist, all of them will try to propagate the attribute changes to the parent. This will result in the last change on any child overriding any change done by any other children. Remove all the attributes from the template to prevent the propagation. Only extended attributes can be propagated upwards.
