struct xsltNumberData

struct xsltNumberData {

This data structure is just a wrapper to pass xsl:number data in.

typedef xsltNumberData *xsltNumberDataPtr;

struct xsltFormatNumberInfo

struct xsltFormatNumberInfo {
    int	    integer_hash;	/* Number of '#' in integer part */
    int	    integer_digits;	/* Number of '0' in integer part */

};

This data structure lists the various parameters needed to format numbers.
