Viacheslav Kabanovich commented on JBIDE-12990:
-----------------------------------------------

The message is added by 'org.eclipse.wst.xml.core.xml validator. The delegate class that performed validation is org.eclipse.wst.xml.core.internal.validator.XMLValidator. It expects that namespace references XML schema. Instead, the reference targets a tag library, which XML validator considers as a schema with syntax errors. Here are examples of nested errors:

{code}
schema_reference.4: Failed to read schema document 'file:/home/slava/JBossTools/jbosstools-jst/plugins/org.jboss.tools.jst.web.kb/taglibs/tld/facelets_jsf_core.taglib.xml', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.
{code}

{code}
s4s-elt-invalid: Element 'facelet-taglib' is not a valid element in a schema document.
{code}

{code}
s4s-elt-schema-ns: The namespace of element 'facelet-taglib' must be from the schema namespace, 'http://www.w3.org/2001/XMLSchema'.
{code}

{code}
s4s-elt-character: Non-whitespace characters are not allowed in schema elements other than 'xs:appinfo' and 'xs:documentation'. Saw 'The core JavaServer Faces custom actions that are independent of'.
{code}
