       8 . The screed joint of  claim 7  wherein said flexible attachment assembly member has an accordion-like shape.  
   
   
       9 . The screed joint of  claim 7  wherein said flexible attachment assembly comprises: 
 a first intermediate web extending from said first distal end of said first screed wall, said first intermediate web having a proximal end spaced from said proximal end of said first screed wall; and    a second intermediate web extending between said proximal end of said first intermediate web and said distal end of said second screed wall.    
   
   
       10 . The screed joint of  claim 7  wherein said first attachment flange and said second base flange are substantially coplanar.  
   
   
       11 . The screed joint of  claim 7  further comprising at least one weep hole through at least one of said first screed wall and said first intermediate web.  
   
   
       12 . A screed joint for use in connection with a first lower wall and a second upper wall supported on the first lower wall and defining a joint therebetween, said screed joint comprising: 
 a lower screed portion attachable to the first lower wall adjacent the joint;    an upper screed portion attachable to the second upper wall to slidably overlap a portion of the lower screed portion to define a space between said upper screed portion and said lower screed portion; and    sealant material in said space between said upper screed portion and said lower screed portion.    
   
   
       13 . The screed joint of  claim 12  wherein said sealant material comprises: 
 a flexible backer member; and    flowable sealant material.    
   
   
       14 . The screed joint of  claim 12  wherein said upper screed portion comprises: 
 an upper attachment flange;    a first screed wall extending from said upper attachment flange and having a distal end spaced from said upper attachment flange; and    a second screed wall extending from said distal end of said first screed wall and wherein said lower screed portion comprises:    a lower attachment flange; and    a lower screed wall extending from said lower attachment flange and defining said space between said lower screed wall and said second screed wall.    
   
   
       15 . The screed joint of  claim 14  wherein said lower screed wall has a screed lip formed on a distal end thereof.  
   
   
       16 . The screed joint of  claim 14  wherein said second screed wall has second support flange on a proximal end thereof for sliding engagement with said lower attachment flange.  
   
   
       17 . The screed joint of  claim 14  wherein said distal end of said lower screed wall is located a first distance from said lower attachment flange and wherein said distal end of said first upper screed wall is located a second distance from said upper attachment flange that is greater than said first distance.  
   
   
       18 . The screed joint of  claim 14  wherein said first screed wall forms an obtuse angle with respect to said upper attachment flange.  
   
   
       19 . The screed joint of  claim 18  further comprising at least one weep hole through at least one of said first screed wall and said second screed wall.  
   
   
       20 . A wall structure, comprising: 
 a first wall having a first wall surface defining a first plane;    a second wall supported on said first wall and forming a joint therebetween, said second wall having a second wall surface;    a screed joint comprising: 
 a first attachment flange attached to said second wall; 
 a first screed wall extending from said first attachment flange at a first obtuse angle, said first screed wall having a distal end spaced from said first attachment flange;  
 a second screed wall extending from said distal end of said first screed wall, said second screed wall forming a second angle therewith;
