Ranges

A range specification is a dimension name, followed by an optional negation character (‘!’), and a starting and ending value separated by a colon, surrounded by parentheses or square brackets. Either the starting or ending values can be omitted. Parentheses indicate an open endpoint that doesn’t include the adjacent value. Square brackets indicate a closed endpoint that includes the adjacent value.
