Hi, As I have read on previous posts, oXygen classifies mixed content based on the current contents of an element, is this correct? If so, is it possible for oXygen to classify elements based on the declarations made in the DTD or Schema it is associated to? I know that the work around for this is to specify the pattern of elements that you want to preserve the whitespace in the preferences or to manually insert an xml:space="preserve" attributes for these elements, but if an XML is associated with a DTD or a Schema then you can tell whether whitespace in that element is ignorable or not. Currently what I've been doing is for every project I have to specify in the pattern listing all the mixed content elements that are defined in the DTD/Schema so that when I do a pretty print the whitespace is preserved and this method is very troublesome. Is there anymore workaround for this other than the ones I mentioned above? Or can this be considered as an added feature for a future version of the product? Thanks, Jeff
