Description
DFDL spec isn't totally clear how whitespace is treated in a schema when using a DFDL Expression.
I think leading and trailing whitespace (not just space) needs to be trimmed before searching for the '{' and '}' to recognize a DFDL Expression. This allows expressions to be formatted on new lines in the schema eg:
<dfdl:setVariable ref="b"> { ... some long XPath expression ... }
</dfdl:setVariable>
Section 6.3
"• DFDL expression
The property is an xs:string the value of which is a DFDL subset XPath 2.0 expression that returns a value derived from other property values and/or from the DFDL infoset. Leading and trailing spaces are allowed and ignored."
Section 6.3.2
"The rules for recognizing DFDL expressions are
• Must start with a '{' in the first position and end with '}' in the last position."
