## Attributes and Elements

The following sections describe attributes, child elements, and parent elements.

### Attributes

Attribute Description
closeTimeout A TimeSpan value that specifies the interval of time provided for a close operation to complete. This value should be greater than or equal to Zero. The default is 00:01:00.
name A string that contains the configuration name of the binding. This value should be unique because it is used as an identification for the binding. Starting with .NET Framework 4, bindings and behaviors are not required to have a name. For more information about default configuration and nameless bindings and behaviors, see Simplified Configuration and Simplified Configuration for WCF Services.
openTimeout A TimeSpan value that specifies the interval of time provided for an open operation to complete. This value should be greater than or equal to Zero. The default is 00:01:00.
