• layerTransformation (literal string or DFDL expression) - XSD NCNames - all reserved. In the future this may become extensible allowing QNames to be used.
• layerEncoding (literal string or DFDL expression)
• layerLengthKind - same values as dfdl:lengthKind
• layerTerminator (literal string or DFDL expression) - used with dfdl:layerLengthKind 'delimited'
• layerLength (literal string or DFDL expression) - used with dfdl:layerLengthKind 'explicit'
• layerLengthPattern - used with dfdl:layerLengthKind 'pattern'
• layerLengthUnits - must be "bytes" (only allowed value for now. - makes clear that the length will be in whole bytes)
• (TBD layer properties for when dfdl:layerLengthKind is 'prefixed' - such time as that is supported, if ever.)

A layered sequence has a mandatory layer alignment (analogous to mandatory text alignment). This is 1 byte for all currently specified layer transforms; in the future this may change.
