The DFDL specification doesn't seem to say that a leading plus sign is ignored. Here's what it says:
If 'lax' and dfdl:textNumberRep is 'standard' then grouping separators are ignored, leading and trailing whitespace is ignored, leading zeros are ignored and quoted characters may be omitted.
Nothing about ignoring plus signs in that.
