kxmlgui.xsd add Separator append attribute
Review Request #126253 - Created Dec. 5, 2015 and submitted
Add an append attribute to the Separator Element of the kxmlgui.xsd
added to Krazy now. no longer see the xmllint warnings in kolf
kpartgui.dtd is mostly used for documentation purposes.
kxmlgui.xsd is "more recent" (relatively speaking) and can also be used for validating files (xsd is more powerful for this).
Maybe we can kill the DTD file these days.
