See the next section for the possible EA types.   

Note:  "Standard Extended Attributes (SEAs) have a dot (.) as a prefix. 
       This identifies the extended attribute as a SEA. The leading dot is 
       reserved, so applications should not define extended attributes 
       that start with a dot. Also, extended attributes that start with 
       the characters $, @, &, or + are reserved for system use." 
       Be aware that the information about the types of the Standard 
       Extended Attributes in the Control Program Guide and Reference is 
       not correct!
