Willem Salembier commented on WSS-625:
--------------------------------------

Spec leads discussed about this here:
https://lists.w3.org/Archives/Public/w3c-ietf-xmldsig/2001AprJun/0183.html

The overall sentiment was to better remove the 76 length requirement and CRLF 
ending to avoid c14n issues. The amendment  was added to 
https://www.w3.org/TR/xmlschema-2/#base64Binary 

Still both forms are permitted and Base64 parsers should be permissive,. It’s 
just odd to see & #13 characters in XML-DSIG Base64 elements 

> Use RFC4648 base64 encoder for signature values and BST

> {{Base64.getMimeEncoder()}} use {{Base64.getEncoder()}}
> Perhaps make it configurable
