Jeppesen are merely a collator and distributor of aeronautical data gathered at (often) minimal expense from national (State) documents. That they sometimes reformat and thereby induce errors is a concern to most reputable State regulators but there is little that can be done to regulate them directly.
To answer the OP's conundrum: the ICAO SARPS (as detailed in the various Annexes and PANS) are translated into the State regulations (rules) and differences notified to the international community and ICAO by advice to ICAO in accordance with Article 38 of the Convention and noted in the State AIP.

OK, between these two posts I'm getting somewhere.
So each country has their own AIP, which upon further Googling is an Aeronautical Information Publication. Per the Wikipedia article on AIPs, they're standardized by countries through an agreement with ICAO. They tend to come in three parts- General, Enroute, and Aerodromes. So if one wants to learn about a specific country's rules, they'd have to dig through that country's AIP themselves or use Jeppesen to summarize the rules and variances.
OK, and continuing with GNE's narrative and doing a little more Googling, ICAO has SARPs (Standards and Recommended Practices) contained in 19 annexes and PANS (Procedures for Air Navigation Services) contained in six documents. None are regulatory (ICAO can't enforce) but the world apparently uses them as a basis for their own country's rules.
And if a country deviates from ICAO's SARPs and PANs, Article 38 asks that the country notify ICAO of those changes. Is there a place where one can find one country's deviations from ICAO SARPs and PANs if they "self disclose" these deviations?
So is that pretty much it? Am I missing anything?
