Returns the value of a service attribute with the specified name attached to the specified element. (See also "What are Service Attributes?" below.)

If the element has no service attribute with that name associated with it, the function will return null.

However, null can be also a legitimate value of a service attribute. To distinguish between two situations, use hasServiceAttr() function.

Parameters:

element

The element whose service attribute is requested. If not specified, the generator context element is assumed by default, which is the same as the call: getServiceAttr(contextElement, attrName)
attrName
The name of the requested service attribute.

Returns:

The value of the service attribute or null, if no service attribute with the specified name is attached to the specified element.
