 | Range Query | `StudyDate`/`PatientBirthDate`          | `{attributeID}={value1}-{value2}`. For date/ time values, we support an inclusive range on the tag. This range is mapped to `attributeID >= {value1} AND attributeID <= {value2}`. If `{value1}` isn't specified, all occurrences of dates/times prior to and including `{value2}` are matched. Likewise, if `{value2}` isn't specified, all occurrences of `{value1}` and subsequent dates/times are matched. However, one of these values has to be present. `{attributeID}={value1}-` and `{attributeID}=-{value2}` are valid, however, `{attributeID}=-` is invalid. |
