- Specification: XRPLF/XRPL-Standards#239 - Amendment: `SingleAssetVault` - Implements a vault feature used to store a fungible asset (XRP, IOU, or MPT, but not NFT) and to receive shares in the vault (an MPT) in exchange. - A vault can be private or public. - A private vault can use permissioned domains, subject to the `PermissionedDomains` amendment. - Shares can be exchanged back into asset with `VaultWithdraw`. - Permissions on the asset in the vault are transitively applied on shares in the vault. - Issuer of the asset in the vault can clawback with `VaultClawback`. - Extended `MPTokenIssuance` with `DomainID`, used by the permissioned domain on the vault shares.

* A serializable number.
|
|
*
|
|
* This type is-a `Number`, and can be used everywhere that is accepted.
|
|
* This type simply integrates `Number` with the serialization framework,
|
|
* letting it be used for fields in ledger entries and transactions.
|
|
* It is effectively an `STAmount` sans `Asset`:
|
|
* it can represent a value of any token type (XRP, IOU, or MPT)
|
|
* without paying the storage cost of duplicating asset information
|
|
* that may be deduced from the context.
