Configure library layers for your deployment
You configure the layers for your multi-level libraries by editing the library-layers.xml configuration file.

</library><layer> element per layer. A layer has the following attributes:
					| Attribute | Description | 
|---|---|
| id | Specifies the level of the library layer. Note: The level must be unique within the library-layers.xml configuration
									file. Library layers start at 1, the highest level. You can add as many layers as necessary. A library or product can reference content from a library that is at the same level as a sibling library, or at a lower level as a child library. | 
| name | Contains the descriptive name of the library layer. Related DRM dialogs use it to identify the layer. | 
| description | Contains a short explanation about the library layer. | 
| isDefault | Specifies the layer as the default layer. Note: Only one layer can be set as the
										default,  isDefault="yes".The default layer is used for backward compatibility. When an existing library version is released, if it does not have a layer level associated to it, it is assigned this default layer. | 
You can add other layers, as appropriate for your deployment. Creating multiple layers increases the complexity of the IXIA Dynamic Release Management.
| Note: Please contact your MadCap Software
								DITA specialist to help you carefully plan before implementing
								multi-level libraries in your deployment, since they increase the
								complexity of the IXIA CCMS.  |
