Hi Michael,

I received your follow-up recommending that we add seconds-from-1970() and
deprecate seconds-from-dataTime() to make future updating to XForms 2.0/XPath
2.0 easier.

This only seems to add confusing complexities to XForms 1.1 in order to make at
best a minor improvement to the future update capabilities.  The update of 1.x
content to XForms 2.0 should have much bigger issues than this.
It is also by no means clear that a form author undergoing such a large update
of content would even want to retain the 1970 semantic anyway because the
typical call of these functions is to do date math and comparisons.

Finally, it should be noted that the current estimated (optimistic) timeframe
for an XForms 2.0 recommendation is the end of 2010.

Best regards,
John Boyer
