					 xsltTransformContextPtr ctxt, 
					 const xmlChar * URL)

Check if the resource is allowed to be read

Function: xsltCheckWrite

int	xsltCheckWrite			(xsltSecurityPrefsPtr sec, 
					 xsltTransformContextPtr ctxt, 
					 const xmlChar * URL)

Check if the resource is allowed to be written, if necessary makes some preliminary work like creating directories

int	xsltSetCtxtSecurityPrefs	(xsltSecurityPrefsPtr sec, 
					 xsltTransformContextPtr ctxt)

Set the security preference for a specific transformation

Function: xsltSetDefaultSecurityPrefs

void	xsltSetDefaultSecurityPrefs	(xsltSecurityPrefsPtr sec)

Set the default security preference application-wide

Function: xsltSetSecurityPrefs

int	xsltSetSecurityPrefs		(xsltSecurityPrefsPtr sec, 
					 xsltSecurityOption option, 
					 xsltSecurityCheck func)
