The access statement determines whether the attribute value can be read or written. The access statement is optional and can appear only once in the attribute definition.
The syntax for the access statement is:
access = method
method can take the following values: read-only, read-write, write-only.
The access statement is not specified, the default access method used for the attribute definition is read-only.
Note: It is highly recommended that keyed values be assigned an access type of read-only.
If you are using the DMI browser to display a key attribute with an access type other than read-only, do not attempt to change the key attribute's value or set the attribute's value to be the same as that of another key attribute. This can cause unpredictable results.
