The proposal to allow padding to minimum length on output consists of new property ouputMinLength Separate pad properties for string, number and calendar types new textxxxxPad property to control padding . Moved from from textxxxxxxJustification 1 Padding
Property Name Description outputMinLength String. Only used when textStringPad, textNumberPad or textCalendarPad is ’m inlength’.
Specifies the minimum output length of this element using either a fixed number or an expression to refer to an element earlier in the data,.
Annotation: dfdl:element (all simple types)
1.1 Properties Specific to Strings with Text representation
Property Name Description textStringPad Enum Valid values ‘none’, ‘fixed’, ‘minLength’
Controls how an item is justified on output when the actual length of a text string is different from the specified length.
Controls how an item is trimmed on input if textTrimKind is padChar
If ‘none’ the string is expected to match the length.
Otherwise:
- If lengthKind results in a fixed length: If shorter than the specified length it is padded with the pad character. If longer than the specified length it is truncated.
- If lengthKind is ‘prefixed’: If the string is longer than any specified maximum length it is truncated.
textStringJustification Enum Valid values ‘left’, ‘right’, ‘center’
‘center’ adds equal padChars before and after the string contents if the string is too short. It adds one extra padChar befor e if needed.
‘center’ truncates equal numbers of characters before and after if the string is too long. It removes one extra character at the fro nt of the string if needed.

Annotation: dfdl:element (simple type ‘string’)
textStringPadCharacter String. The padding character used as the default for justification of text elements.
In fixed width character sets this must contain a full single character representation. So if hex entities are used, enough hex bytes must be supplied to provided the full width of a character.
In variable width character sets, this character must be a minimum- width character unless it is specified as an entity (see section TBD Entities)

1.3 Properties Specific to Calendar with Text representation
Property Name Description textCalendarPad Enum Valid values ‘none’, ‘fixed’, ‘minLength’
