     <state name="#ANY">This state is for patterns that can be recognized in any state.</state>
     <state name="DEFAULT">This state is for patterns that occur at the beginning of an expression.</state>
     <state name="OPERATOR">This state is for patterns that are defined for operators.</state>
     <state name="QNAME">When a qualified name is expected, and it is required to remove ambiguity from patterns that look like keywords, this state is used.</state>
     <state name="NAMESPACEDECL" if="xquery core">This state occurs inside of a namespace declaration, and is needed to recognize a NCName that is to be used as the prefix, as opposed to allowing a QName to occur.  (Otherwise, the difference between NCName and QName are ambiguous.)</state>
     <state name="NAMESPACEKEYWORD" if="xquery core">This state occurs at places where the keyword "namespace" is expected, which would otherwise be ambiguous compared to a QName.  QNames can not occur in this state.</state>
     <state name="XMLSPACE_DECL" if="xquery core">This state occurs at places where the keywords "preserve" and "strip" is expected to support "declare xmlspace".  QNames can not occur in this state.</state>
     <state name="ITEMTYPE">This state distinguishes tokens that can occur only inside the ItemType production.</state>

     <state name="VARNAME">This state differentiates variable names from qualified names.  This allows only the pattern of a QName to be recognized when otherwise ambiguities could occur.</state>
     <state name="START_TAG" if="xquery core">This state allows attributes in the native XML syntax, and marks the beginning of an element construction. Element constructors also push the current state, popping it at the conclusion of an end tag. In the START_TAG state, the string "&gt;" is recognized as a token which is associated with the transition to the original state.</state>
     <state name="ELEMENT_CONTENT" if="xquery core">This state allows XML-like content, without these characters being misinterpreted as expressions. The character "{" marks a transition to the DEFAULT state, i.e. the start of an embedded expression, and the "}" character pops back to the ELEMENT_CONTENT state.  To allow curly braces to be used as character content, a double left or right curly brace is interpreted as a single curly brace character.  The string "&lt;/" is interpreted as the beginning of an end tag, which is associated with a transition to the END_TAG state.</state>
     <state name="END_TAG" if="xquery core">When the end tag is terminated, the state is popped to the state that was pushed at the start of the corresponding start tag.</state>
     <state name="XML_COMMENT" if="xquery core">The "&lt;--" token marks the beginning of an XML Comment, and the "--&gt;" token marks the end.  This allows no special interpretation of other characters in this state.</state>
     <state name="PROCESSING_INSTRUCTION" if="xquery core">In this state, only lexemes that are legal in a processing instruction name are recognized.</state>
     <state name="PROCESSING_INSTRUCTION_CONTENT" if="xquery core">In this state, only characters are that are legal in processing instruction content are recognized.</state>
     <state name="CDATA_SECTION" if="xquery core">In this state, only lexemes that are legal in a CDATA section are recognized.</state>
     <state name="QUOT_ATTRIBUTE_CONTENT" if="xquery core">This state allows content legal for attributes. The character "{" marks a transition to the DEFAULT state, i.e. the start of an embedded expression, and the "}" character pops back to the original state.  To allow curly braces to be used as character content, a double left or right curly brace is interpreted as a single curly brace character.  This state is the same as QUOT_ATTRIBUTE_CONTENT, except that apostrophes are allowed without escaping, and an unescaped quote marks the end of the state.</state>
