IBM Installation Manager and the Not-Well-Formed Markup

I saw this: -

ERROR: Failed to read response file.
  ERROR: Problem in /mnt/installIIM186.rsp at line 5: The markup in the document following the root element must be well-formed.
00:00.52 ERROR [main] com.ibm.cic.agent.core.application.HeadlessApplication run
  Failed to read response file.
    Problem in /mnt/installIIM186.rsp at line 5: The markup in the document following the root element must be well-formed.

whilst trying to install IBM Installation Manager 1.8.7, using a response file: -

I dug around, and found out where I'd gone wrong.

I needed to have the line: -

<agent-input acceptLicense='true'>

as per this: -
