I don't think there is a way to achieve what you want. As you say,
trimming pad chars takes precedence over applying escape scheme.
I wondered if you could define the escapeBlockStart and End as "%WSP*; and
%WSP*;" respectively but the white space entities are not allowed as
escape character or in escape block start/end.

Subject: [DFDL-WG] how to trim inside of escape block?
Sent by: "dfdl-wg"
I have a CSV file
Some lines look like this
a,b," started with spaces, appearing right after the escape block
start ",c,d,e
I reviewed the spec, and I see that pad characters appear outside of the
quotation marks (escape block start/end).
What I'm trying to do is remove the whitespace after the escape block
start, and before the escape block end. This is just spurious whitespace,
appears because some of these CSV files were edited by people.
In my data the quoting characters are not always present. They are only
there if a comma appears in the data string.
Is there a technique for getting rid of the leading/trailing whitespace
inside the escape block start/end that I have forgotten?
