Hi,

We have made a partial commit that fixes some of your reported bugs. But
there are also some bugs that need some clarification.

Tests OBJECTS_OR_SCRIPT 4 and OBJECTS_OR_SCRIPT 5 aren't on CVS so we
couldn't check exactly where is the problem.

Only images considered "Included Resources" are now checked.

directive)

Caching directives are not taken into account.

When we implemented this test we interpreted that each stylesheet should
be checked individually. Let me move this issue to Jo.

We're currently working on this, it's already fixed for stylesheets
included by the style tag (although not commited yet) but not for linked
styles (included by link tag)

It crashed when trying to check an CSS resource that was actually
another type of document. Now the exception is catched and ignored.

Added in moki document an "imageInfo" block to each object that is an
image. The "imageInfo" block has the same structure as the respective
"imageInfo" block existing for images.

We couldn't reproduce this error.
