Hi Roger,
Error messages have schema locations. Are you sure that the error message
wasn't about a specific choice branch having a dfdl:choiceBranchKey=" "? If
the error message is actually talking about such a dfdl:choiceBranchKey
attribute, it is telling you to replace that dfdl:choiceBranchKey=" " with
dfdl:choiceBranchKey="%SP;" (that is, use a DFDL entity for that whitespace
character).

Subject: EXT: How to use choiceDispatchKey when the key is a blank character?

Hi Folks,
I am reading a subsection code (1 character) into this element:
<xs:element name="Subsection_Code" type="xs:string"
dfdl:lengthKind="explicit" dfdl:length="1"/>
Some subsection codes are the blank character.
Then I use choiceDispatchKey on that element that holds the subsection code:
<xs:choice dfdl:choiceDispatchKey="{Subsection_Code}">
I get this error message when I run my DFDL schema:
Schema Definition Error: For choiceDispatchKey, the string ( ) must not contain
any whitespace. Use DFDL Entities for whitespace characters.
Is there a workaround?
/Roger
