Re: [xsl] problem with scientific notation and leading whitespaces

[Michael Kay <mike@xxxxxxxxxxxx>]

The output, on the evidence supplied, does not conform to either the XSLT 1.0
or 2.0 specification.

In 1.0 numbers should never be displayed in scientific notation.

In 2.0, there should not be any whitespace added.

So you should raise this as a bug (non-conformance) with whoever (if anyone)
supports xsltproc. If there's a workaround, that's where you're likely to find
out about it. Alternatively, switch to a different processor.
