Unwanted Dead key in own character set

Dear list,

unexperienced with xkb, I have created an own keyboard layout that tries  
to give me the possibility to enter German Umlauts in a conventient way,  
without sacrificing the comfort of my US keyboard. Though I had to adjust  
the file a small number of times to keep up with X11 development, the file  
is working well. It is more or less a hack of us-intl and is attached  
below (also available with a longer description from  

My only problem is, that the German capital U-Umlaut (Ü) seems to be  
mapped to a dead key (called by RightAlt-U). That is, I have to press it  
twice for it to show up. I assume that it was mapped to a dead key in the  
layout that I inherited from (US/ASCII). All other keys work fine. How can  
I prevent U-umlaut to be dead?
