Remove unused name attributes

For <value> elements inside <resource> ones, the name attribute and the
text of the element was the same, but our scripts only parsed the text.
So remove the redundant code that's ignored anyway.

Remove unused list elements

Change them to choice, what was probably really meant here: allow one of
the values, not a whitespace-separated list of one or more values.

Also, clean up nested choices.
