What famous standards publishing services do you know?

Question

Standardization

For example. There are RFC standards and I only know https://tools.ietf.org/html/rfc5789 as a service for publishing them. Please write well-known publishing services. Perhaps you know a framework or CMS with similar functionality

* Разметка TXT
* Автоконверт в файл, загрузки 
    * PDF
    * DOC
* HTML версия

For example, something similar for GOST and so on.

It's not very clear what you want. RFC is not a format, it is a series of standards. The IETF is the organization that publishes RFCs, and there are no other "publishing services" for them, but there is https://www.rfc-editor.org/ for RFC developers that functions as an IETF contractor. Old standards are available only in text, new ones are published in several formats, inside XML is used, the format of which is defined in RFC2629/RFC7749/RFC7991, there are several tools that translate this format into HTML, nroff (man), etc, for example
