This is certainly allowed in XML schema.. In the sequence you can have multiple elements with same name as long as their type is identical which is the case in your example. I think from XPath perspective, it would be treated like array and if true dldl:occursCount should return 2. .

From: Mike Beckerle <mbeckerle.dfdl@gmail.com> To: dfdl-wg@ogf.org, Date: 02/28/2013 07:44 PM Subject: [DFDL-WG] is this legal Sent by: dfdl-wg-bounces@ogf.org I can't find clarity on this: <sequence> <element name="foo" type="int" dfdl:lengthKind="explicit" dfdl:length="1"/> <element name="bar" type="int" dfdl:lengthKind="explicit" dfdl:length="1"/> <element name="foo" type="int" dfdl:lengthKind="explicit" dfdl:length="1"/> <element name="bar" type="int" dfdl:lengthKind="explicit" dfdl:length="1"/> </sequence> Is this allowed? If so, then the XPaths for accessing the 2nd foo would be foo[2], and the path "foo" would be ambiguous or could be treated as identifying an array. In which case one could do an expression dfdl:occursCount("foo") and get back 2 ?? Or am I completely missing the boat here? -- Mike Beckerle | OGF DFDL Workgroup Co-Chair | Tresys Technology | www.tresys.com -- dfdl-wg mailing list dfdl-wg@ogf.org https://www.ogf.org/mailman/listinfo/dfdl-wg
