For example, the expression GPL-2.0 OR BSD-3-Clause describes a relationship where one can choose between two licenses, but it does not imply any specific interpretation of how to choose or the way to interpret the respective licenses. Another example is GPL-2.0 AND BSD-3-Clause. The AND operator represents that the code from two different works has been combined (e.g., for example a program is created by combining two different files under two different licenses). It does not specifically imply whether the resulting expression is a derivative work or a collection. The legal determination of whether the two licenses are compatible or how one might interpret the marriage of these licenses is left to the user or distributor of the file or program. It is conceivable that different organizations could come to different legal determinations for the same license expression.

The license identifier “GPL-2.0” (without the “+”) is still a valid identifier. After using SPDX in practice it was realized that there are several benefits to treating the “+” as a separate operator. The expression GPL-2.0+ is a valid expression in SPDX 2.0 and has the same semantic meaning as the deprecated license identifier “GPL-2.0+”. The only difference is that the “+” is an operator  that stands for “or a later version”. The “+” can now be used with other licenses in addition to the GPL and LGPL (e.g., EPL-1.0+). It reduces license list bloat, that is, we do not need to add every possible license with a “+” for all possible license cases one may encounter. This also applies to license exceptions. By introducing the “+” and “WITH” operators we can more simply and conveniently represent the myriad of special exceptions without needing to clutter the license list with all the different combinations that include the GPL and LGPL and later versions of the license. That is, we wanted to avoid adding the following to the license list:</div></td><td class='diff-marker'>+</td><td style="color:black; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div>The license identifier “GPL-2.0+” will be depreciated in the updated version of the SPDX License List that accompanies the SPDX 2.0 specification release.
