The ironjacamar.xml descriptor files across the WildFly testsuite are either missing proper XML schema declarations or are using outdated/incorrect schema references.

Fixing the declaration causes schema validation failures and prevents proper validation of the deployment descriptors.

1. Missing or incomplete XML schema declarations (no xmlns/xsi:schemaLocation)
2. Incorrect namespace: Using http://www.jboss.org/ironjacamar/schema instead of http://www.ironjacamar.org/doc/schema
3. Outdated schema version: Referencing ironjacamar_1_2.xsd instead of ironjacamar_1_3.xsd
4. Incorrect element ordering causing schema validation failures (elements not ordered according to XSD sequence requirements)
