xsltNewStylesheet ()
Create a new XSLT Stylesheet

Load and parse an XSLT stylesheet

Free up the memory allocated by sheet
xsltIsBlank ()
| int         xsltIsBlank                     (xmlChar *str); | 
Check if a string is ignorable
xsltFreeStackElemList ()
Free up the memory allocated by elem
xsltDecimalFormatGetByName ()
Find decimal-format by name
xsltParseStylesheetProcess ()
parse an XSLT stylesheet adding the associated structures
xsltParseStylesheetOutput ()
parse an XSLT stylesheet output element and record
information related to the stylesheet output
xsltParseStylesheetDoc ()
parse an XSLT stylesheet building the associated structures
xsltParseStylesheetImportedDoc ()
parse an XSLT stylesheet building the associated structures
except the processing not needed for imported documents.
xsltLoadStylesheetPI ()
This function tries to locate the stylesheet PI in the given document
If found, and if contained within the document, it will extract 
that subtree to build the stylesheet to process doc (doc itself will
be modified). If found but referencing an external document it will
attempt to load it and generate a stylesheet from it. In both cases,
the resulting stylesheet and the document need to be freed once the
transformation is done.

format-number() uses the JDK 1.1 DecimalFormat class:
http://java.sun.com/products/jdk/1.1/docs/api/java.text.DecimalFormat.html
Structure:
  pattern    := subpattern{;subpattern}
  subpattern := {prefix}integer{.fraction}{suffix}
  prefix     := '\\u0000'..'\\uFFFD' - specialCharacters
  suffix     := '\\u0000'..'\\uFFFD' - specialCharacters
  integer    := '#'* '0'* '0'
  fraction   := '0'* '#'*
  Notation:
   X*       0 or more instances of X
   (X | Y)  either X or Y.
   X..Y     any character from X up to Y, inclusive.
   S - T    characters in S, except those in T
Special Characters:
  Symbol Meaning
  0      a digit
  #      a digit, zero shows as absent
  .      placeholder for decimal separator
  ,      placeholder for grouping separator.
  ;      separates formats.
  -      default negative prefix.
  %      multiply by 100 and show as percentage
  ?      multiply by 1000 and show as per mille
  X      any other characters can be used in the prefix or suffix
  '      used to quote special characters in a prefix or suffix.
xsltParseTemplateContent ()
parse a template content-model
Clean-up the template content from unwanted ignorable blank nodes
and process xslt:text
xsltAllocateExtra ()
Allocate an extra runtime information slot statically while compiling
the stylesheet and return its number
xsltAllocateExtraCtxt ()
Allocate an extra runtime information slot at run-time
and return its number
This make sure there is a slot ready in the transformation context
