[jbosstools-issues] [JBoss JIRA] (JBIDE-20012) Jboss Tools HTML editor not validating syntax using html5 doctype (xhtml doctype is OK)

[Victor Rubezhny (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-20012?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13077020#comment-13077020 ] 

Victor Rubezhny commented on JBIDE-20012:
-----------------------------------------

I've found two problems here:

1) When validator tries to find CMDocument for the <h:body> element it searches the XML Catalog and finds schema in org.jboss.tools.jsf/taglibs/html_basic.taglib.xml file. But the CMDocument created from this schema doesn't contain elements (which are required to validate <h:body> element against).
This schema comes from org.jboss.tools.jsf plug-in.

2) Then I've tried to remove any jsf* plug-ins from Run Configuration and faced the same problem (<h:body> element wasn't validated properly, while clean Eclipse Mars + WTP configuration validates <h:body> tag successfully). In such Run Configuration I've found that there is no schema defined for public ID "http://www.w3.org/1999/xhtml" (which exists in clean Eclipse Mars + WTP installation). So, the validation has started to work properly after I've added the following XML Catalog entry:

{code}
Entry element:		URI
Location:			http://www.w3.org/2002/08/xhtml/xhtml1-strict.xsd
URI:   				http://www.w3.org/2002/08/xhtml/xhtml1-strict.xsd
Key type:			Namespace name
Key:				http://www.w3.org/1999/xhtml
{code}

[~akazakov] Can we replace our schema (org.jboss.tools.jsf/taglibs/html_basic.taglib.xml) by the default one from Eclipse JEE bundle? Will it break our own Validation and Content Assist features?
