 For multi-level buildings where <<sub-address,sub-addresses>> need to be assigned, the <<sub-address,sub-address>> number SHALL concate two parts:
 
-* Alphanumeric characters to represent the level within the building, including a level type code and/or level number
-** Level type codes:

 ** Where there are multiple levels for a particular https://linked.data.gov.au/def/building-level-type[building level type], a number MAY be added after the level type code.
 ** Level numbers SHALL increase with height for all above ground levels

 ** To be allocated in logical sequence to each <<address-site, address site>>
 ** For <<address-site, address sites>> 1 to 9, a preceding zero will be added
 ** In instances where insufficient numbers are available for all <<address-site, address sites>> on a level, an alternative method that ensures unique unambiguous numbering may be used.
