Item
X.getStringValueCS().toString()
returns a string that is equal to
X.getStringValue()
.
Note that two CharSequence values of different types should not be compared using equals(), and
for the same reason they should not be used as a key in a hash table.
If the calling code can handle any CharSequence, this method should
be used. If the caller requires a string, the Item.getStringValue()
method is preferred.getStringValueCS
