+ writeScanOn: strm
+ 	"Implement this method for a text attribute to define how it it should be written
+ 	to a serialized form of a text object. The form should correspond to the source
+ 	file format, i.e. use a scan character to denote its subclass.
+ 	As TextAttributes are stored in RunArrays, this method is mostly called from RunArray>>#write scan.
+ 	For reading the written information see TextAttribute class>>#scanFrom:"
