10<shortdesc>When you validate your XML file, the XML validator will check to
11see that your file is valid and well-formed.</shortdesc>

17<context><p>The XML editor will process XML files that are invalid or not
18well-formed. The editor uses heuristics to open a file using the best interpretation
19of the tagging that it can. For example, an element with a missing end tag
20is simply assumed to end at the end of the document. As you make updates to
21a file, the editor incrementally reinterprets your document, changing the
22highlighting, tree view, and so on. Many formation errors are easy to spot
23in the syntax highlighting, so you can easily correct obvious errors on-the-fly.
24However, there will be other cases when it will be beneficial to perform formal

26it in the Navigator view, right-clicking it, and clicking <uicontrol>Validate</uicontrol>.
27Any validation problems are indicated in the Problems view. You can double-click
28on individual errors, and you will be taken to the invalid tag in the file,
29so that you can make corrections.</p></context>

36can set up a project's properties so that different types of project resources
37are automatically validated when you save them. From a project's pop-up menu,
