Hi Robert...
There are lots of different ways you can hack your XSLT to conform
more to your desired format but probably the easiest is simply:
<input>
<xsl:if test="boolean(@checked)">
<xsl:attribute name="checked">checked</xsl:attribute>
</xsl:if>
</input>
Actually, the boolean function isnt even necessary. I put it there to
better represent the format you suggested. In reality, no matter its
value (you can extend the test to check for this by simply adding '=
xyz' or whatever you may want to check for) if the checked attribute
exists the test will evaluate to true, if not, false and the contained
xsl:attribute element will not be added to the <input/> element.
Compared to your example obviously this is a lot more code to get the
same functionality but the fact that this will work and the desired
sample will not obviously presents a choice of verbosity over
verbosity/complexity instead of the desired choice of simplicity over
simplicity/verbosity. Keep in mind that with XPath 2.0 this all
changes to give you exactly what it is you are looking for... well,
not the exact syntax but close enough to put a smile on your face for
sure.
Hope this helps! BTW... You may find some more ideas over on XSL-List
