Re: [xsl] xbind:module == xsl:script + an essential layer of indirection

Eugene,

These two approaches are semantically identical.

The only difference is that with the current <xsl:script>
proposal, if you list three languages for the same
namespace uri, then you save a little typing by doing:

<xsl:stylesheet xmlns:date="http://datestuff.com/xslt/extensions">
   <xsl:script implements-prefix="date" language="lang:yyyy"
               src="http://datestuff.com/xslt/extension/impl/dates.xyz"/>

   <xsl:script implements-prefix="date" language="lang:zzzzz"
               src="http://datestuff.com/xslt/extension/impl/dates.xyz"/>

   <xsl:script implements-prefix="date" language="anotherlang:qqqqq"
               src="http://datestuff.com/xslt/extension/impl/dates.xyz"/>

whereas with your proposal, you repeat the namespace uri
each time instead of using its shortcut/prefix name:

<xsl:stylesheet> 
   <xsl:script implements="http://datestuff.com/xslt/extensions" 
               language="lang:yyyy"
               src="http://datestuff.com/xslt/extension/impl/dates.xyz"/>

   <xsl:script implements="http://datestuff.com/xslt/extensions"
               language="lang:zzzzz"
               src="http://datestuff.com/xslt/extension/impl/dates.xyz"/>

   <xsl:script implements="http://datestuff.com/xslt/extensions" 
               language="anotherlang:qqqqq"
               src="http://datestuff.com/xslt/extension/impl/dates.xyz"/>
