Is there a way in cryptography to add the <host> and <attrdesc> attributes to the relative_name?

Hello developer, I saw in RFC5280 that…

Blockquote
When the LDAP URI scheme [RFC4516] is used, the URI MUST include a field containing the distinguished name of the entry holding the CRL, MUST include a single that contains an appropriate attribute description for the attribute that holds the CRL [RFC4523], and SHOULD include a (e.g., <ldap://ldap.example.com/cn=example%20CA,dc=example,dc=com? certificateRevocationList;binary>). Omitting the (e.g., ldap:///cn=CA,dc=example,dc=com?authorityRevocationList;binary) has the effect of relying on whatever a priori knowledge the client might have to contact an appropriate server.

I know how to add values like CN, DC, etc., to the relative_name , but I haven’t found the code to add the <host> and <attrdesc> attributes. Can the cryptography library add the <host> and <attrdesc> attributes to the relative_name ?
