Description

User reported that dfdl:terminator=" %LF;" causes the following exception, likely due to the space at the beginning of property value. If this property (and likely others) start or end with a space, it should probably be an SDE, since they probably meant to do something like dfdl:terminator="%SP;%LF;". Exception below:
