There is an deployment failure with XML parsing error as 'urn:jboss:shared-session-config:1.0 tracking-mode' for session sharing in an EAR on the JBoss EAP 7.
There is an example of META-INF/jboss-all.xml in JBoss EAP 7 development guide as below. However it can't be deployed.

3.7.4.1. REFERENCE OF SHARED SESSION CONFIG OPTIONS

Example: META-INF/jboss-all.xml

<jboss umlns="urn:jboss:1.0">
  <shared-session-config xmlns="urn:jboss:shared-session-config:1.0">
    <max-active-sessions>10</max-active-sessions>
    <session-config>
      <session-timeout>0</session-timeout>
      <cookie-config>
        <name>JSESSIONID</name>
        <domain>domainName</domain>
        <path>/cookiePath</path>
        <comment>cookie comment</comment>
        <http-only>true</http-only>
        <secure>true</secure>
        <max-age>-1</max-age>
      </cookie-config>
    </session-config>
    <tracking-mode>COOKIE</tracking-mode>
  </shared-session-config>
  <replication-config>
    <cache-name>web</cache-name>
    <replication-granularity>SESSION</replication-granularity>
  </replication-config>
</jboss>

There is an error for <tracking-mode> element as below and if it removed, there is an error for <replication-config> element:

With my investigation, there is shared-session-config_1_0.xsd [2] schema for definition and SharedSessionConfigParser_1_0.java [3] class for parsing. However, there is structure mismatch for <replication-config> element and missing for <tracking-mode> element in the parsing class.
