add a key definition to a stylesheet
| style: | an XSLT stylesheet | 
| name: | the key name or NULL | 
| nameURI: | the name URI or NULL | 
| match: | the match value | 
| use: | the use value | 
| inst: | the key instruction | 
| Returns: | 0 in case of success, and -1 in case of failure. | 
void xsltFreeDocumentKeys (xsltDocumentPtr idoc)
Free the keys associated to a document
| idoc: | a XSLT document | 
void xsltFreeKeys (xsltStylesheetPtr style)
Free up the memory used by XSLT keys in a stylesheet
| style: | an XSLT stylesheet | 
xmlNodeSetPtr xsltGetKey (xsltTransformContextPtr ctxt,
const xmlChar * name,
const xmlChar * nameURI,
const xmlChar * value)
Looks up a key of the in current source doc (the document info on @ctxt->document). Computes the key if not already done for the current source doc.
| ctxt: | an XSLT transformation context | 
| name: | the key name or NULL | 
| nameURI: | the name URI or NULL | 
| value: | the key value to look for | 
| Returns: | the nodeset resulting from the query or NULL | 
void xsltInitCtxtKeys (xsltTransformContextPtr ctxt,
xsltDocumentPtr idoc)
Computes all the keys tables for the current input document. Should be done before global varibales are initialized. NOTE: Not used anymore in the refactored code.
| ctxt: | an XSLT transformation context | 
| idoc: | a document info |
