Thanks for the review, Carl.

Done.  I caught this mistake when handling the last comment from Daniel's review.

Section 6 now reads:

   If slh_sign is implemented in a hardware device such as hardware
   security module (HSM) or portable cryptographic token,
   implementations might want to avoid is sending the full content to
   the device.  By including signed attributes, which necessarily
   include the message-digest attribute and the content-type attribute
   as described in Section 5.3 of [RFC5652], the much smaller set of
   signed attributes are sent to the device for signing.

   Following the approach in the previous paragraph is essentially the
   same as using SLH-DSA in pre-hash mode, which means that a hash of
   the content is passed to the SLH-DSA signature operation instead of
   the full message content.  For this reason, this document only
   specifies the use od SLH-DSA pure mode.


> Add “algorithms” to the end of the second sentence in section 1.2

Done.  In the following paragraph, I also changed "large-scale quantum computers" to "cryptographically relevant quantum computers (CRQC)" to align with the terms in PQUIP.
