Save is carried out using the Save changes to Attribute Lists toolbar button. Any changes you have made are validated, and any validation errors are advised in a dialog. You may not proceed with the Save until you have resolved them.
At Save, if an attribute list's Use for placeholders property is checked, new placeholder attributes are created and saved to the folder defined by the list's Placeholder attribute folder property. Any subsequent saved changes to attributes' names at the list are reflected at placeholder attribute file names.
Following a successful save, attribute lists are displayed in alphabetical order. All lists' states are updated to Unchanged. Any deleted lists are removed from display.
