This dialog box allows you to change the autocompletion and schema settings for the XML Editor. You can access the Options dialog box from the Tools menu.
Auto Insert
Close tags
If the autocompletion setting is checked, the editor automatically adds an end tag when you type a right angle bracket (>) to close a start tag, if the tag is not already closed. This is the default behavior.
The completion of an empty element does not depend on the autocompletion setting. You can always autocomplete an empty element by typing a backslash (/).
Attribute quotes
When authoring XML attributes, the editor inserts the =" " characters and positions the caret (^) inside the double quotes.
Selected by default.
Namespace declarations
The editor automatically inserts namespace declarations wherever they are needed.
Selected by default.
Other markup (Comments, CDATA)
Comments, CDATA, DOCTYPE, processing instructions, and other markup are auto-completed.
Selected by default.
Network
Automatically download DTDs and schemas
Schemas and document type definitions (DTDs) are automatically downloaded from HTTP locations. This feature uses System.Net with auto-proxy server detection enabled.
Selected by default.
Outlining
Enter outlining mode when files open
Turns on the outlining feature when a file is opened.
Selected by default.
Caching
Schemas
Specifies the location of the schema cache. The browse button ( ...) opens the Directory Browse dialog box at the current schema cache location. You can select a different directory, or you can select a folder in the dialog, right-click, and choose Open to see what is in the directory.
