Identifying Non-Standardized Algorithm Names via URI

Sensitivity Label: Public

Hello,

I was wondering if someone could describe how a system should identify algorithms that have not been officially standardized when used with XML-based cryptography.

For example, if a system intends to utilize DSA with SHA3-256 for digital signature generation or verification, how should this be referenced as a URI for an "Algorithm" attribute?

It is understood that, since the algorithm is NOT considered standardized, the sender and recipient may both be specifically configured to recognize the value. This is more a question of expectations and formality.

Thanks,
Chris Forrester
