[jira] Commented: (JCR-1718) repository-1.5.dtd: change order of main elements

["Jukka Zitting (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/JCR-1718?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12622453#action_12622453 ] 

Jukka Zitting commented on JCR-1718:
------------------------------------

I'd rather not break things for people who may be validating the repository.xml. At least a change like this requires an update to the DTD version.

Also, for better backwards compatibility I'd make it (with an informal rule that you can have only a single Cluster configuration element):

<!ELEMENT Repository (Cluster?,FileSystem,DataStore?,Security,Workspaces,Workspace,Versioning,Cluster?,SearchIndex?)> 

Or even (allowing more flexibility at the cost of some extra code and potential confusion):

<!ELEMENT Repository (Cluster|FileSystem|DataStore|Security|Workspaces|Workspace|Versioning|SearchIndex)*>

> Currently the order of elements in repository.xml is:
> <!ELEMENT Repository (FileSystem,Security,Workspaces,Workspace,Versioning,SearchIndex?,Cluster?,DataStore?)>
> I would like to change it to
> <!ELEMENT Repository (Cluster?,FileSystem,DataStore?,Security,Workspaces,Workspace,Versioning,SearchIndex?)>
> because I think that makes more sense.
> Currently XML validation is disabled, and therefore the order of elements in the DTD does not need to match the repository.xml file. However as soon as XML validation is enabled, repository.xml files that use the wrong order will no longer work (the repository can not be started).
> There is a request to enable XML validation at http://issues.apache.org/jira/browse/JCR-1462
