What specific section or headline is this issue about?

Parameters

What information was incorrect, unhelpful, or incomplete?

Although the current description:

loneProperty

A lone Unicode property name or value, following the same syntax as value. It specifies the value for the General_Category property, or a binary property name.

does exclude Script values from being used as loneProperty, but using such values alone is valid in ICU and therefore in most common softwares based on it. For developers familiar with ICU but not with the JS Unicode mode, this discrepancy makes it harder to debug.

What did you expect to see?

A few words warning about the discrepancy.

Do you have any supporting links, references, or citations?

No response

Do you have anything more you want to share?

The references for regular expressions on MDN are of great quality and value. They save me a lot of time during the learning of regular expressions 👍
