Making an addon both Plone 4 and Plone 5 compatible

I'm trying to make an addon both Plone 4 and Plone 5 compatible. The problem I'm running into is the profiles/default XML.

Plone 5: I have a registry.xml for registering CSS Plone 4: I have a cssregistry.xml for registering CSS

I was hoping Plone 4 would ignore the registry.xml but it picked it up and then crashes during the install in Plone 4. Is there a solution to this?

What you said works great when you add: 

xmlns:zcml="http://namespaces.zope.org/zcml"

To the top configuration. Just a note for any future people who need this.

You can have multiple profiles pointing to different profile directories (they are defined in configure.zcml), and the Plone docs have examples of how to conditionally evaluate ZCML:

<include zcml:condition="have plone-4" package=".package" />
<include zcml:condition="not-have plone-4" package=".otherpackage" />

There's also a straight "evaluate content if condition is met" by having zcml:condition on a configure.
