When 'startup_wait' option is added to 'mysql' resource in '/etc/cluster/cluster.conf', using 'system-config-cluster' results in 'Relax-NG validity error' in Red Hat Cluster Suite 5

Issue

• Even though 'startup_wait' is a valid option for 'mysql' resource in '/etc/cluster/cluster.conf', using 'system-config-cluster' results in syntax error
• The error message is '/etc/cluster/cluster.conf:78: element fs: Relax-NG validity error : Element service has extra content: fs
  Relax-NG validity error : Extra element rm in interleave'
• The error message is '/etc/cluster/cluster.conf:2: element cluster: Relax-NG validity error : Element cluster failed to validate content
  /etc/cluster/cluster.conf fails to validate'
