While I agree, I want to note that \s is any whitespace not just a space
in a regexp. The backslash notation allows you to configure values that
are not (or at least not easily) entered otherwise.

Here's a syntax version without | but with a magic whitespace attriburte:

lib.fo = TEXT
lib.fo {
 value =  * Hello World *
 trim = 1
 trim.charList = *
 trim.charList.trimWhiteSpace = 1
}

And here's yet another one where charList is a comma separated list and
any number is meant to be a code point (note that you have to use code
points if you want to trim number!):

lib.fo = TEXT
lib.fo {
 value =  * Hello World *
 trim = 1
 trim.charList = *,32
}
