I have recently switched from working on *Android* in `Eclipse` to working on `iOS` apps in *Xcode*. I really liked the Eclipse XML editor interface (which has features like auto-complete, CDATA documentation tooltips, linking to schema libraries, and xml validation). Since Xcode is tough on my CPU and Eclipse is also fairly cpu-consuming (and having both open would be hectic), I have opted to not use Eclipse for XML editing, and to find something light-weight that fits the needs listed above.

So, as the title states, **are there any free, light-weight xml and xml-schema editors available?** I looked into CAM editor by Oracle, but could not find a way to add XML Schema catalogs. Apart from that, I have had little luck finding something.
