Extended attributes (EA) can contain pointers to data stored in other places.
This data type indicates that the data contained in another EA associated with the file object should be included into the current EA.
For example, the following EA value contains the string "Hello", followed by the data in the EA named AB.STUFF, followed by the string "Bye".
EA_MVMT 0000 0003 EAT_ASCII 0005 Hello EAT_EA 0008 AB.STUFF EAT_ASCII 0003 Bye
