multiproject:site fail if sub-projects has a & on POM

If a sub-project has a & in its description, multiproject:site fails, even though site:generate works fine on the sub-project:

xdoc:jelly-transform:

I haven't checked how projects-overview.xml is generated yet, but it is probably applying a XSL on the sub-project POM, and that transformation is replacing & for &.
