## 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
