DITA Hotspots

I am using FrameMaker 2015 to create DITA 1.2 xml files

I am trying to create hotspots on images:

<imagemap><image href = "../Maps/_images/lifecycle_partition.png"

scale = "40" />

<area><shape>rect</shape>

<coords>2,0,53,59</coords>

<xref outputclass = "fm:" keyref = "access_control_policies">Access

control policies</xref></area></imagemap>

However, the image does not have a hotspot and the text "rect", "2,0,53,59" and "Access Control Policy" appears under the image.

The text appears on the Document View, PDF and HTML5 outputs.

When I try using the Hotspot mode in the graphic tools, I get a warning on save of:

Framemaker does not support DITA multiple graphic object in a single frame.

So, how do I create hotspots using FrameMaker DITA?
