Which of these is the most efficient way of rendering html?
Answers to such questions are always dependent on the XSLT processor you
are using, and the simple answer is to measure it: in this case I
suspect that you will find that the difference in execution time is
insignificant, though the shorter stylesheet will probably be faster to
compile.
To look at it another way: do you have a performance problem? If you do,
this change isn't going to solve it. If you don't, why are you worrying
about it?

It's obvious which one is easier to code, but which one would
actually parse more quickly? In the abbreviated examples
below, the difference, of course would be negligible...but
consider a page of a few thousand lines of rendered HTML.
SCENARIO #1:
----------------------
<?xml version = "1.0" encoding = "UTF-8"?>
<xsl:stylesheet version = "1.0" xmlns:xsl =
"http://www.w3.org/1999/XSL/Transform";>
<xmlRoot>
<table
border="1" cellspacing="1">
<tr>
<td>abc</td>
</tr>
</table>
</xmlRoot>
</xsl:stylesheet>
SCENARIO #2:
----------------------
<?xml version = "1.0" encoding = "UTF-8"?>
<xsl:stylesheet version = "1.0" xmlns:xsl =
"http://www.w3.org/1999/XSL/Transform";>
<xmlRoot>
<xsl:element name="table">
<xsl:attribute name="border">
<xsl:text>1</xsl:text>
</xsl:attribute>
<xsl:attribute name="cellspacing">
<xsl:text>1</xsl:text>
</xsl:attribute>
<xsl:element name="tr">
<xsl:element name="td">
<xsl:text>abc</xsl:text>
</xsl:element>
</xsl:element>
</xsl:element>
</xmlRoot>
</xsl:stylesheet>
