What is the logical operator between the elements of array licenses?

[nmalygin-com]

CycloneDX v1.6 specification provides two alternatives to specify multiple licenses for a component (in the components list):

• SPDX License Expression

• A list of SPDX licenses and/or named licenses

In the case of an SPDX license expression, the operators (AND, OR, etc.) are explicitly specified in the expression. But the specification does not clearly indicate how to interpret the list of licenses (as elements between which there is an AND operator or an OR operator). Please help me understand the type of logical operator in the corresponding list.
