Do I need to add this to any of the following files where I find moreInformation referenced:

• TestCoverageLevel.txt
• missingOk.txt
• prettyPath.txt
• PathHeader.txt
• PathDescriptions.md
• IdToPath.java
• ExampleDependencies.java
• TestXPathTable.java

Also, about this test failure:

Error:  (TestExampleGenerator.java:327)  Error: No example:	<[>	"//ldml/characters/nestedBracketReplacement[@source=\"([^\"]*+)\"]",

I want this to not appear in survey tool, because it's easy to get wrong and it hardly ever changes. How should I do this? Should I add it to TestExampleGenerator::DELIBERATE_EXCLUDED_EXAMPLES like moreInformation is?

I was worried about not every language using parentheses (thereby a substitution could fail) but parentheses are pretty universal for localePattern https://www.unicode.org/cldr/charts/48/by_type/locale_display_names.locale_name_patterns.html#4c3249dbb329101c

Can you test out the algorithm that would implement this on RTL locales? I want to make sure it doesn't cause problems.

Naming-wise, I like "innerBracket" (a bracket that is in a bracket) over "nestedBracketReplacement", but I defer to you.

Per usual, that's my 2 cents but I am happy to follow your lead. I'm deferring the accept to someone who is a more frequent Design group member.
