There exists a precedent for using a compound asset_reference https://github.com/ChainAgnostic/namespaces/blob/main/stacks/caip19.md

| For Example: | ||
| ``` | ||
| canton:mainnet-global/cip-56:decentralized-usdc-interchain-rep%3A%3A12208115f1e168dd7e792320be9c4ca720c751a02a3053c7606e1c1cd3dad9bf60ef/USDCx |

| asset_namespace = cip-56 | ||
| asset_reference = percentEncode({instrumentId.admin}) + "." + percentEncode({instrumentId.id}) |

I think a brief description of percentEncode might be appropriate (for instance, what exactly gets encoded? Now at least these . and : are required)
| asset_type = {chain_id}/slip44:6767 | ||
| ``` | ||
|
|
||
| Hence, for `CC` on `canton:mainnet-global`, the `asset_type` is `canton:mainnet/slip44:6767`. |

Is it mainnet or mainnet-global? The CAIP2 defines it as mainnet-global.
| canton:{mainnet|testnet|devnet}-dedicated-name | ||
| ``` | ||
|
|
||
| The complete network identifier, prefix and dedicated name together, **MUST** satisfy the CAIP-2 reference production `[-_a-zA-Z0-9]{1,32}`, leaving at most 24 characters for `{dedicated-name}`. |

Technically it's at most 25 characters in that case, since devnet is shorter than the others?
|
|
||
| ## Limitations | ||
|
|
||
| The `account_address` lenght **MUST** be <= 128 characters. The party namespace takes 64 characters, the url encoded colons 4 characters, the `canton:` prefix 7 characters, and thus leaving 53 characters for the `{networkIdentifier}:{partyHint}`. |

Wouldn't it be percent encoded colons and it's 6 characters, not 4.
Isn't the party namespace 68 characters because of the prefix?
Also, some of the arithmetics seem confusing here, I'm not sure it's 32 characters for the party hint, but I haven't done the math.

I would consider using the prefix 1220 for both examples, it's weird having one with and one without
