Hallo Stefan,

Is this right:

If I want to encode a xmss_ots_signature (e.g. as part of a xmss_signature) I have to write at first 4 byte for the " xmss_algorithm_type type" discriminator followed by 4 byte for an specific arm?

Thanks,
Andreas

Hi Andreas,

thanks for pointing out the issues and please excuse the inconvencience.

The easy fix for which I'd settle as suggested by David is to use underbars.

> - some enum bodies end with  ",}", RFC4506 requests "}" here
You're right. Please omit the commas.

It's just a numeric identifier, as pointed out by Carsten, defined as
ots_algorithm_type. Does this help or do you have any further
questions about it?

No, there isn't, yet. But we could e.g. go for an errata for the RFC.

Kind Regards,
Stefan (speaking for the authors)
