                                                         const xmlNodePtr cur,
                                                         SECItem *a);Converts the node content from CryptoBinary format
(http://www.w3.org/TR/xmldsig-core/sec-CryptoBinary)
to a SECItem. If no SECItem object provided then a new
one is created (caller is responsible for freeing it). 
| arena: |  the arena from which to allocate memory |  
| cur: |  the poitner to an XML node. |  
| a: |  a SECItem object to hold the BigNum value |  
| Returns : |  a pointer to SECItem produced from CryptoBinary string
or NULL if an error occurs. |  
 
xmlSecNssNodeSetBigNumValue ()int                 xmlSecNssNodeSetBigNumValue         (xmlNodePtr cur,
                                                         const SECItem *a,

(http://www.w3.org/TR/xmldsig-core/sec-CryptoBinary)
and sets it as the content of the given node. If the
addLineBreaks is set then line breaks are added
before and after the CryptoBinary string.
