() (parentheses for grouping)ΒΆ
Use parentheses, e.g. ( and ), to avoid confusion when grouping together more than two licenses in an expression. Parentheses may be nested.
For example:
# SPDX-License-Identifier: Apache-2.0 AND (MIT OR BSD-3-Clause)
indicates that the recipient (1) must comply with Apache-2.0, and also (2) must comply with their choice of either MIT or BSD-3-Clause.
