Mapping Part Names to ZIP Item Names
To map part names to ZIP item names the package implementer shall perform, in order, the following steps [M3.4]:
Convert the part name to a logical item name or, in the case of interleaved parts, to a complete sequence of logical item names.
Remove the leading forward slash (/) from the logical item name or, in the case of interleaved parts, from each of the logical item names within the complete sequence.
The package implementer shall not map a logical item name or complete sequence of logical item names sharing a common prefix to a part name if the logical item prefix has no corresponding content type. [M3.5]
