[ssax-sxml] SXML and XML digital signature (XML DSig): how?

[Hoehle, Joerg-C. <Joe...@t-...>]

Hi,

I have a need to use XML DSig. My idea was to get some ready-made Java =
component (e.g. from the Apache security project) that implements XML =
DSig and somehow integrate that with SXML (to stay in my beloved Lisp =
world instead of becoming a Java-eater).
http://xml.apache.org/security/index.html

Good idea? Bad idea?

I wonder whether SXML is of much use in such a context. I probably need =
to build a string representation of the XML I want to sign/verify. Then =
feed that to the Apache signature (Java) component which will itself =
build a DOM.
Or I write a SXML->Java/w3c.DOM converter.
And I probably may need a w3c.dom->SXML converter as well.
All in all, the XML document looks like it will be twice in the =
machine: as SXML and as a w3c.dom also.

What I want is to generate testcases: plenty of good and bad XML =
documents that will be fed to a foreign application.

Thanks for your ideas,
