[stringtemplate-interest] Attributes in derived templates.

Hi.  it seems to me to you are not passing anything to template  
someContent, therefore "$attr$" will have no value and be empty.

  sorry for the delay and my absence on the string template list.  I  
will be picking up string template development during the summer.  I  
am almost done with version 3 release of ANTLR.  The book will be  
printed in early May, which includes examples using ANTLR and ST for  
source is code generation!
