OpenLayers uses innerHTML (breaks under XHTML)

[openlayers]

OpenLayers writes to the innerHTML properties in the DOM tree. This is forbidden when using XHTML, so OpenLayers breaks if it is embedded in a page served as application/xml+xhtml. Notably this affects Safari but not FireFox (which seems to allow writes to these properties anyway).

Code with problems that are easy to fix:

• LayerSwitcher
• MousePosition (I think? I can't imagine anyone using a seperator with HTML in it)
• Control.Panel
• Control.PanZoomBar
• Control.Scale

Hard to fix:

• Popup
• EventPane
• Attribution
• ScaleLine

Upside: All layers and navigation controls are clean.

Downside: Attribution is a default control now, so the default map is not xhtml clean.

WhoCaresSide: XHTML is a lost cause anyway :)
