seeking a better way to have a blank line followed by an indented dl

Description

Summary: We used <t><br/></t> to get the desired output. Seems that ideally we wouldn't use <br/> for this case. Would be helpful to be able to indent a whole <dl>.
Example: https://www.rfc-editor.org/authors/rfc9381.html (e.g., section 4, 4.1, 4.2, 4.3, and others)

Details:
For example (original):

   Parameters used:

      (n, e) - RSA public key

      K - RSA private key (its representation is implementation-
      dependent)

      k - length in octets of the RSA modulus n (k must be less than
      2^32)

   Fixed options (specified in Section 4.4):

      Hash - cryptographic hash function

      hLen - output length in octets of hash function Hash

      suite_string - an octet string specifying the RSA-FDH-VRF
      ciphersuite, which determines the above options

With the assumption that we'd like the nested lists to be <dl> bc it's accurate semantically, here are some options: (test files were updated only for the portion above above)
A) <dl> for outer items, then nested <dl>

• Con: <t><br/></t> has to be used to get a blank line after the outer item.
• Example: the current file (https://www.rfc-editor.org/authors/rfc9381.html#section-4)

B) <ul bare="true" empty="true"> <li> for outer items, each of which has a nested <dl>

• Con: yields good text output, but bad HTML and PDF (bc the <dl>s are not indented)
• Example: https://www.rfc-editor.org/v3test/test9381_bad_ul_in_html.html#section-4 (bad) vs. https://www.rfc-editor.org/v3test/test9381_bad_ul_in_html.txt (good)

C) <t> for outer items, then a <dl>.

• Con: the <dl>s are not indented.
• Example: https://www.rfc-editor.org/v3test/test9381_t_dl.html#section-4

What was done in the original (draft-irtf-cfrg-vrf-15.xml)
D) <t> for outer items, then a <ul empty="true">

• Cons: not accurate semantically; definitions that are longer than one line do not wrap as desired; past guidance to the RPC was to not use <ul empty="true"> to create indentation.

Potential improvements here

• better documentation around acceptable use for <br/>
• B seems to be a bug bc the other outputs should match.
• a new attribute on <dl> to indicate "put a blank line after dt" (this is not accomplished with newline="true")
  (FWIW, testing of changes to the spacing attribute, did not help here.)
• the ability to have an indented <dl> without nesting it at all. perhaps as a new attribute. (Note: the indent attribute on a dl currently has to do with indenting the lines after the first line. it does not have to do with indenting the dl as as whole.)

Code of Conduct

• I agree to follow the IETF's Code of Conduct

Start by reviewing the current file for RFC 9381 section 4 and compare the test9381_t_dl.html, test9381_bad_ul_in_html.html, and test9381_bad_ul_in_html.txt examples with the original draft. Determine which nested dl spacing and indentation behavior should be supported, then update the relevant tests and documentation so the HTML, text, and PDF outputs match the agreed result.
