For Schematron validations, it is possible to select the validation phase.Marking Validation Errors and WarningsA line with a validation error or warning will be marked in the editor panel by underlining the error region with a redcolor. Also a red sign will mark the position in the document of that line on the right side ruler of the editor panel. Thesame will happen for a validation warning, only the color will be yellow instead of red.The ruler on the right side of the document is designed to display the errors and warnings found during the validationprocess and also to help the user to locate them more easily. The ruler contains the following areas:• Top area containing a success validation indicator that will turn green in case the validation succeeded or red otherwise.• Middle area where the error markers are depicted in red . The number of markers shown can be limited by modifyingthe setting Window > Preferences > oXygen > Editor > Document checking > Maximum number of problemsreported per document .Clicking on a marker will highlight the corresponding text area in the editor. The error message is displayed both inthe tool tip and in the error area on the bottom of the editor panel.Status messages from every validation action are logged into the Console view.If you want to see all the validation error messages grouped in a view you should run the action Validate which isavailable both on the toolbar and on the XML menu. This action collects all error messages in the Problems view ofthe Eclipse platform if the validated file is in the current workspace or in a custom Oxygen view called Errors if thevalidated file is outside the workspace.Validation Example - A DocBook Validation ErrorIn the following DocBook 4 document the content of the listitem element does not match the rules of the DocBook4 schema, that is docbookx.dtd.Article TitleSection1 Title
