Hello,
Below is a patch to invoke the XML validator when an XML file is saved (from the XOT browser) or uploaded. It does not verify XML files uploaded in a zip file (i.e. as part of a project). Since it seems that XML files can have slightly different MIME types, we only ensure that the last part is '/xml'.
The patch includes a change from an earlier patch which invokes the antivirus/file extension/mime type checks for uploaded files. That is, this patch includes all the changes I have applied to the original v3.0 source file.
