Notice that there really is whitespace in your stylesheet. The processor
has to figure out whether you mean it to be there literally or just for
visual formatting. Xslt has rules for this situation, and the rules say to
eliminate such whitespace-only nodes (unless, in a stylesheet, they appear
in an xsl:text element - there are other rules for whitespace-only nodes in
the source document).
Apparently this processor is not doing the stripping. Perhaps it is a user
option that you can turn off or on. Check the documentation for the .NET.
Also, it would be simpler to write your snippet this way, using a literal
result element and attribute value syntax -
<newElement newAttrib='{sampleElement/@attrib}'/>
This should get through the proccessor, bug or not, OK because it has no
embedded whitespace.

That is what I get with both MSXML4 and Saxon (as expected).
I would suggest 1) using the simplified form I show above, 2) if for some
reason you have to use xsl:element and xsl:attribute (unlikely), see if
there is a transformer option to control the behavior, and lastly, 3),
eliminate extra whitespace like this (the email system may cause this to
wrap) -
<xsl:element name="newElement"><xsl:attribute name="newAttrib"><xsl:value-of
select="sampleElement/@attrib" /></xsl:attribute></xsl:element>
