I came back to Intellij Idea after a few months because my boss allowed me to return :) but I installed IntelliJ IDEA 2016.1 and now I cannot see the validation and autocomplete in xml, xsd, xsl files. Everithing that I try to add with Ctrl + Space is in "No suggestion".
In addition, when I try to close a tag in a xsd file, the editor is not allowing me to do that!
The most extrange thing is I have the previous version installed in another PC and there is all working well so, I tried to find the option in settings but I cannot get the solution. What is the option to "enable" this features?
