Overview
A grid is displayed, listing all existing attribute lists:

Within the grid, the following read-only columns are displayed:
Name
Is Placeholder List
State
When no attribute lists have been configured, an advisory message is displayed.
Create new Attribute List
This is carried out in the toolbar. On clicking the button, a new attribute list is added to the grid, and placed in an appropriate alphabetical position.
Its Name is “New attribute list” (an incrementable integer can be added to the name to ensure uniqueness).
Configure existing Attribute List
This is carried out in the tab set. If you configure an attribute list that has been saved previously, its State is set to Edited.
Delete selected Attribute List
This is carried out in the toolbar. A deleted attribute list's State is set to Deleted. Its row text color is set to red. You may no longer select a deleted row.
Save changes to Attribute Lists
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.
Refresh
This option reloads the contents of the interface from the operational database. If changes have been made, a ‘Save Changes?’ dialog is shown.
Create Parameter Attributes
When you select an Unchanged attribute list at which Use for placeholders is unchecked, a Create Parameter Attributes button is made available at the Configuration Workbench toolbar.
The button is used to create parameter attributes based on the attributes in the attributes list.
Clicking the button displays the Choose Folder to Save Parameter Attributes folder chooser dialog. You can select a folder within the RPI file system and select OK to create parameter attributes based on the attributes within the attribute list. An information message advises that the parameter attributes were saved to the selected folder.
If any attributes were unable to be saved, due to their Key Name property values matching the names of files already present in the folder, a warning message advises of number of attributes thus affected. Selecting Cancel at the dialog removes it from display.
Properties at a parameter attribute created from an attribute list are set as follows:
Name: set to the attribute list's attribute's Key Name.
Description: set to the attribute list's attribute's Description.
Default value: set to the attribute list's attribute's Default Value.
Linked Wiki Page: set to the attribute list's attribute's Wiki Page.
