Eclipse autocomplete in xml editor

How to configure eclipse to autocomplete at least class full path on Ctrl+Space in 开发者_StackOverflowxml editor? I am using springsource tool suite (its same eclipse), there IDE understands when it is beans config file and auto complete works. But elsewhere in just xml file, this doesn't work :(

You can try Rinzo XML editor if you like which does what you are asking for:
