/**
* Test part name Open Packaging Convention compliance.
*
* (Open Packaging Convention 8.1.1 Part names) :
*
* The part name grammar is defined as follows:
*
* part_name = 1*( "/" segment )
*
* segment = 1*( pchar )
*
* pchar is defined in RFC 3986.
*
* The part name grammar implies the following constraints. The package
* implementer shall neither create any part that violates these constraints nor
* retrieve any data from a package as a part if the purported part name
* violates these constraints.
*
* A part name shall not be empty. [M1.1]
*
* A part name shall not have empty segments. [M1.3]
*
* A part name shall start with a forward slash ("/") character. [M1.4]
*
* A part name shall not have a forward slash as the last character. [M1.5]
*
* A segment shall not hold any characters other than pchar characters. [M1.6]
*
* Part segments have the following additional constraints. The package
* implementer shall neither create any part with a part name comprised of a
* segment that violates these constraints nor retrieve any data from a package
* as a part if the purported part name contains a segment that violates these
* constraints.
*
* A segment shall not contain percent-encoded forward slash ("/"), or backward
* slash ("\") characters. [M1.7]
*
* A segment shall not contain percent-encoded unreserved characters. [M1.8]
*
* A segment shall not end with a dot (".") character. [M1.9]
*
* A segment shall include at least one non-dot character. [M1.10]
*
* A package implementer shall neither create nor recognize a part with a part
* name derived from another part name by appending segments to it. [M1.11]
*
* Part name equivalence is determined by comparing part names as
* case-insensitive ASCII strings. [M1.12]
