In MapServer, it is recommended that the name not contain spaces, special characters, or begin with a number (which could cause problems through interfaces such as OGC services)

Help pane

When you click on an entry in the Editing pane a description will appear in this pane for the highlighted entry. If the line contains an error or warning, then that will be shown as well.
