And the “(without the tag and length bytes)” should not be in parenthesis, as it is not an aside but a key requirement.

[CW] I meant something like this (which also corrects a typo in the third word): “The unique identifier is constructed by concatenating the base64url-encoding (see Section 5 of [RFC4648]) of the bytes of the keyIdentifier field of certificate's Authority Key Identifier (AKI) extension (see Section 4.2.1.1 of [RFC5280]), a literal period, and the base64url-encoding of the bytes of the DER encoding of the certificate's Serial Number (without the tag and length bytes).”

Or you could break it into multiple sentences.
The unique identifier is constructed by concatenating the base64url-encoding of the bytes of the keyIdentifier field of certificate's Authority Key Identifier (AKI) extension, a literal period, and the base64url-encoding of the bytes of the DER encoding of the certificate's Serial Number (without the tag and length bytes). The encoding is defined in Section 5 of [RFC4648] and the AKI extension is defined in Section 4.2.1.1 of [RFC5280].
