This definition can be viewed as a hypernym of the Orchard note commitment, and will allow maintaining a single commitment instance for the note commitment, which will be used both for pre-ZSA Orchard and ZSA notes.

1. We require that :math:`\forall (\mathsf{AssetBase},\mathsf{v^{AssetBase}}) \in \mathsf{assetBurn}\ ,\ \mathsf{AssetBase} \neq \mathcal{V}^{\mathsf{Orchard}}`. That is, Native Assets are not allowed to be burnt.
1. We require that :math:`\forall (\mathsf{AssetBase},\mathsf{v^{AssetBase}}) \in \mathsf{assetBurn}\ ,\ \mathsf{AssetBase} \neq \mathcal{V}^{\mathsf{Orchard}}`. That is, ZEC or TAZ is not allowed to be burnt.
2. We require that for every :math:`\forall (\mathsf{AssetBase},\mathsf{v^{AssetBase}}) \in \mathsf{assetBurn}\ ,\ \mathsf{v^{AssetBase}} \neq 0`.
3. We require that there be no duplication of Custom Assets in the :math:`\mathsf{assetBurn}` set. That is, every :math:`\mathsf{AssetBase}` has at most one entry in :math:`\mathsf{assetBurn}`.
