## license

licenses can be attached to components in CycloneDX SBOMs. The license elements can be used as top-level elements and be given an id so they can be later referred to via the `refid` attribute - see the Ant manual.

### Attributes

Attribute | Description | Required
--- | --- | ---
licenseId | The id of the license. Must be a valid SPDX identifier. | One of the two is required
name | The name of the license.

### Nested elements

#### url

At most one nested url-resource named `url` can be used to specify the URL of the license.

### Examples

Below is a license referencing the license of this Antlib itself.

          <cdx:license
            licenseId="Apache-2.0"
            id="apache-2"
            xmlns:cdx="antlib:org.apache.ant.cyclonedx">
            <url url="https://www.apache.org/licenses/LICENSE-2.0.txt"/>
          </cdx:license>
