A Pure Identity EPC URI Producer SHALL NOT produce as output a string thatbegins with the characters urn:epc:id: that does not satisfy the grammar ofSection 6, including all constraints on the number of characters in variouscomponents. If a Pure Identity EPC URI Producer constructs a Pure Identity EPC URI fromcomponent parts, it SHALL do so in a manner consistent with this specification.The following conformance requirements apply to EPC Tag/Raw URI Consumers:An EPC Tag/Raw URI Consumer SHALL accept as input any string that satisfies theTagURI production of the grammar of Section 12.4, and that can be encodedaccording to Section 14.3 without causing an exception.An EPC Tag/Raw URI Consumer MAY accept as input any string that satisfies theRawURI production of the grammar of Section 12.4.An EPC Tag/Raw URI Consumer SHALL reject as invalid any input string thatbegins with the characters urn:epc:tag: that does not satisfy the grammar ofSection 12.4, or that causes the encoding procedure of Section 14.3 to raise anexception.An EPC Tag/Raw URI Consumer that accepts EPC Raw URIs as input SHALL rejectas invalid any input string that begins with the characters urn:epc:raw: that doesnot satisfy the grammar of Section 12.4.To the extent that an EPC Tag/Raw URI Consumer interprets the contents of an EPCTag URI or EPC Raw URI, it SHALL do so in a manner consistent with thedefinitions of the EPC Tag URI and EPC Raw URI in this specification and thespecifications referenced herein (including the GS1 General Specifications).The following conformance requirements apply to EPC Tag/Raw URI Producers: An EPC Tag/Raw URI Producer SHALL produce as output strings that satisfy theTagURI production or the RawURI production of the grammar of Seciton 12.4,provided that any output string that satisfies the TagURI production must beencodable according to the encoding procedure of Section 14.3 without raising anexception. An EPC Tag/Raw URI Producer SHALL NOT produce as output a string that beginswith the characters urn:epc:tag: or urn:epc:raw: except as specified in theprevious bullet. If an EPC Tag/Raw URI Producer constructs an EPC Tag URI or EPC Raw URI.fromcomponent parts, it SHALL do so in a manner consistent with this specification.Copyright ©2005- 2011 GS1 AISBL, All Rights Reserved.
