## Description ### Macro: XSLT_REGISTER_FUNCTION_LOOKUP
    #define XSLT_REGISTER_FUNCTION_LOOKUP
Registering macro, not general purpose at all but used in different modules. ### Function: xsltDocumentFunction
    void	xsltDocumentFunction		(xmlXPathParserContextPtr ctxt,
    					 int nargs)
Implement the document() XSLT function node-set document(object, node-set?)
`ctxt`: | the XPath Parser context
`nargs`: | the number of arguments
### Function: xsltElementAvailableFunction
    void	xsltElementAvailableFunction	(xmlXPathParserContextPtr ctxt,
    					 int nargs)
Implement the element-available() XSLT function boolean element-available(string)
`ctxt`: | the XPath Parser context
`nargs`: | the number of arguments
### Function: xsltFormatNumberFunction
    void	xsltFormatNumberFunction	(xmlXPathParserContextPtr ctxt,
    					 int nargs)
Implement the format-number() XSLT function string format-number(number, string, string?)
`ctxt`: | the XPath Parser context
`nargs`: | the number of arguments
### Function: xsltFunctionAvailableFunction
    void	xsltFunctionAvailableFunction	(xmlXPathParserContextPtr ctxt,
    					 int nargs)
Implement the function-available() XSLT function boolean function-available(string)
`ctxt`: | the XPath Parser context
`nargs`: | the number of arguments
### Function: xsltGenerateIdFunction
    void	xsltGenerateIdFunction		(xmlXPathParserContextPtr ctxt,
    					 int nargs)
Implement the generate-id() XSLT function string generate-id(node-set?)
`ctxt`: | the XPath Parser context
`nargs`: | the number of arguments
### Function: xsltKeyFunction
    void	xsltKeyFunction			(xmlXPathParserContextPtr ctxt,
    					 int nargs)
Implement the key() XSLT function node-set key(string, object)
`ctxt`: | the XPath Parser context
`nargs`: | the number of arguments
### Function: xsltRegisterAllFunctions
    void	xsltRegisterAllFunctions	(xmlXPathContextPtr ctxt)
Registers all default XSLT functions in this context
`ctxt`: | the XPath context
### Function: xsltSystemPropertyFunction
    void	xsltSystemPropertyFunction	(xmlXPathParserContextPtr ctxt,
    					 int nargs)
Implement the system-property() XSLT function object system-property(string)
`ctxt`: | the XPath Parser context
`nargs`: | the number of arguments
### Function: xsltUnparsedEntityURIFunction
    void	xsltUnparsedEntityURIFunction	(xmlXPathParserContextPtr ctxt,
    					 int nargs)
Implement the unparsed-entity-uri() XSLT function string unparsed-entity-uri(string)
`ctxt`: | the XPath Parser context
`nargs`: | the number of arguments
### Function: xsltXPathFunctionLookup
    xmlXPathFunction	xsltXPathFunctionLookup	(xmlXPathContextPtr ctxt,
    						 const xmlChar * name,
    						 const xmlChar * ns_uri)
This is the entry point when a function is needed by the XPath interpretor.
`ctxt`: | a void * but the XSLT transformation context actually
`name`: | the function name
`ns_uri`: | the function namespace URI
`Returns`: | the callback function or NULL if not found
