# Attribute Value type Reference Sets

An Attribute Value type Reference Set allows associating a value concept with the referenced component. It can be used for a range of purposes where there is a requirement to provide additional information about particular concepts, descriptions, or relationships. The value applied to the referenced component is from the Attribute Value subhierarchy.

To create a new Attribute Value type Reference Set, right-click on the Attribute type navigational node and select the ![](https://content.gitbook.com/content/N7ynFOLTw3W9Zow9AaAJ/blobs/zRSsGMH8hIMoYPqiOw8y/sct_new_attribute_type_refset_icon.png) *New attribute value type reference set...* Context Menu option.

Members can be added the same way as to a Simple type Reference Set. In the Add New Reference Set Wizard, you will need to specify a value for the referenced component.

When adding multiple members at the same time, each will receive the same value specified in the Add New Reference Set Wizard.
{% endhint %}

It is also possible to change the module and the value of the Reference Set member by selecting the module/value cell and clicking on the<img src="https://content.gitbook.com/content/N7ynFOLTw3W9Zow9AaAJ/blobs/nZnV5aWXZpGGKJLZDmLr/more-icon.jpg" alt="" data-size="line">box to invoke the module/value picker.
