How can i view inbuilt Keyword lists and REGEX in DLP?

Question

Hi Everyone,

In the process of developing our custom rules for DLP/AIP. We have exported the standard rules to xml. They start with the following:

<?xml version="1.0" encoding="utf-16"?>
<!--This is the newer version of the default classification definitions.

......
<RulePackage xmlns="http://schemas.microsoft.com/office/2011/mce">

The rule pack contains substantially more than what is detailed here (https://learn.microsoft.com/en-us/microsoft-365/compliance/sensitive-information-type-entity-definitions?view=o365-worldwide) both in terms of rules and the explanation of the Word Lists and REGEX used. We don't want to re-invent the wheel with our custom rules but are unable to actually see what each Microsoft defined Keyword list or REGEX is searching for (e.g. "Regex_mbi_card" , "Keyword_mbi_card" ).

Is there some way we can find out what each item is referring to?

Cheers
