See my links in main reply to OP to get the big picture. Far as XSLT, did you meant the 1985-1995 work he did was &quot;just a 1998 technology?&quot; Or the other way around? ;)<p><a href="http:&#x2F;&#x2F;download.imatix.com&#x2F;mop&#x2F;introduction.html" rel="nofollow">http:&#x2F;&#x2F;download.imatix.com&#x2F;mop&#x2F;introduction.html</a><p><a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=11558465" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=11558465</a><p>Note: I used XML and XSLT back then when they first came out.
