# Version and support information

You can use these extension points to define version and support information for a plug-in. Currently, DITA-OT does not do anything with this information, but it might do so in the future.

package.support.name
  Specifies the person who provides support for the DITA-OT plug-in.
package.support.email
  Specifies the e-mail address of the person who provides support for the DITA-OT plug-in.
package.version
  Specifies the version of the DITA-OT plug-in.

  The value uses the following syntax:

      major.minor.micro.qualifier

  where:

  - major is a number and is required.
  - minor is a number and is optional.
  - micro is a number and is optional.
  - qualifier is optional and can be composed of numerals, uppercase or lower case letters, underscores, and hyphens.

  By default, the package.version value is set to `0.0.0`.

## Example
