There are 4 different version properties for Narayana in WildFly, despite each component that uses the variable being released together (i.e. it's not possible to get a situation where the values of these versions differ).

    <version.org.jboss.jbossts.jbossjts>5.0.0.M2/version.org.jboss.jbossts.jbossjts>
        <version.org.jboss.jbossts.jbossjts-integration>5.0.0.M2</version.org.jboss.jbossts.jbossjts-integration>
        <version.org.jboss.jbossts.jbossxts>5.0.0.M2</version.org.jboss.jbossts.jbossxts>
        <version.org.jboss.jbossts.narayana>5.0.0.M2</version.org.jboss.jbossts.narayana>

As well as being messy, error-prone and more effort to change; it's also caused us a merge conflict (JBTM-1691) that didn't auto-merge correctly.

One version called "version.org.jboss.narayana" would make most sense.
