Yes, <xsl:comment> is really needed in this kind of scenarios. Further, It
is needed when specifying JavaScript files in the xsl sheet as well.
When processed a sheet with following <script> tag via Saxon,
xsl -
<script type="text/javascript" src="{$webhelp.common.dir}
jquery/jquery-1.4.2.min.js">
</script>
this gets transformed to xhtml as -
<script type="text/javascript" src="../common/jquery/jquery-1.4.2.min.js"*/>
*
Since there isn't any text content inside <script> tag, Saxon compress it in
to "/>". This makes the browser not detect the other scripts next to this.
So, I had to change it to following to make it work.
<script type="text/javascript" src="{$webhelp
.common.dir}jquery/jquery-1.4.2.min.js">
* <xsl:comment> </xsl:comment>*
</script>
This issue was with Saxon. xsltproc works as expected.
