Is there such a thing as "in-scope delimiters"?

[Costello, Roger L.]

Hi Folks,

Is there such a thing as in-scope delimiters?

At the field element in the below DFDL schema, what are the in-scope 
delimiters? Comma and newline?

Notice that the field element references a block escapeScheme, which specifies 
that the double quote symbol is used to escape a block of text. If a field's 
value is escaped (via double quotes), then what delimiters are escaped? All 
in-scope delimiters - comma and newline?  /Roger
