Syntax of OID values

I want to make my own tiny rootca.
There are problem with supporting OIDS. I found in documentation about oid_file, but can not decode syntax of values.
DER: works fine, but I want to use more readeable format.

All I can find is the same docs without a tiny working example how to use my defined oids.
sample:
[oid_file]
 1.3.6.1.4.1.311.21.1 msCAversion XCN_OID_CERTSRV_CA_VERSION
 1.3.6.1.4.1.311.21.4 msCRLNextPublish XCN_OID_CRL_NEXT_PUBLISH

[ca.conf]
 oid_file =oid.txt
 ...
[ crl_ext ]
authorityKeyIdentifier=keyid:always
msCAversion = DER:020101
msCRLNextPublish = DER:170D3234303930393131333635395A

with these options all works ok.
>openssl ca -config ca.conf -gencrl -crlexts crl_ext -out crl.pem

but when I try anything like this:
 msCAversion = 1
 msCAversion = INT:01
 msCAversion = INTEGER:0x01
(and many other combinations)

I'll got the same error:
Using configuration from ca.conf
Error checking CRL extension section crl_ext
00CEC9A0FA7F0000:error:11000081:X509 V3 routines:do_ext_nconf:unknown extension:crypto/x509/v3_conf.c:92:
00CEC9A0FA7F0000:error:11000080:X509 V3 routines:X509V3_EXT_nconf_int:error in
extension:crypto/x509/v3_conf.c:48:section=crl_ext, name=msCAversion, value=INTEGER:0x01

Same with datetime, there are no help about it's format:
msCRLNextPublish =UTC
=: UTCTIME:"2024-Sep-09 11:36:59"
 =ANS1.UTCTIME....

How to properly fromat values and please, include it with examples to documentation?

And what to do to make -text outpul with readeable format, not just dump of OIDs? I think, there have to be some global OID config file, but where is it?
