Returns a tree representation of the pattern structure. The hard work is done by formatTree.

Example:

 +---element {}bar
     |
     +---group
         |
         +---oneOrMore
         |   |
         |   +---attribute AnyName
         |       |
         |       +---text
         |
         +---text

The function can be used to display circular ref-pattern structures.

Example:

 <define name="baz">
   <element name="baz">
     ... <ref name="baz"/> ...
   </element>
 </define>

Returns a formated string representation of the pattern structure.

Example:

 Element {}foo (Choice (Choice ( Value = abc, 
 datatypelibrary = http://relaxng.org/ns/structure/1.0, type = token, 
 context (base-uri =file://test.rng, 
 parameter: xml = http://www.w3.org/XML/1998/namespaces, foo = www.bar.baz), 

The function can be used to display circular ref-pattern structures.

Returns a string representation of the pattern structure. (see also: createPatternFromXmlTree)

Example:

 Element {}foo (Choice (Choice (Value ("","token") "abc"
 ("foo","www.bar.baz")]))(Data ("http://www.mysql.com","VARCHAR")
 [("length","2"),("maxLength","5")])) (Element {}bar (Group (Element {}baz

The function can not be used to display circular ref-pattern structures.
