Presumably you mean

static const value_string String[]  = {
  { 1, "String1" },
  { 2, "String2" },
  { 0, NULL }
};

right?  You have to put a terminator - i.e., an element with a null string pointer - at the end of value_string arrays.

What would be in that subtree?  Presumably there would be more than one value in it (a subtree with only one value is generally not that useful); is the value that's decoded with the value_string in question one of the values?  If so, what are the other values?
