Eclipse doesn't show the error icon in the package explorer for xml files that are not well-formed/not valid (after I have saved the file). Is this an intended behaviour? Can I customize that? I wasn't able to find anything on the preferences. I'm using Eclipse Indigo 3.7.2.

Update: I need to perform "Validate" on the file from context. After this validation has finished, the error icon is also shown in the package explorer. This seems unintuitive.

Thank you!
