Hi,
I often find myself defining templates that require numerous parameters.
This leads to two problems:
1. making modifications to the list of parameters - I have to do it in each
template
2. forgetting a parameter, and so losing critical data without receiving a
warning
So I would like to formally specify the interfaces of my templates, using a
syntax like this:
<xsl:interface name="interface1">
<xsl:param name="p1" />
<xsl:param name="p2" />
<xsl:param name="p3" />
</xsl:interface>
<xsl:template name="foo" interface="interface1" />
This saves many, many lines of code in certain kinds of stylesheet, and
eliminates many simple errors.
It also makes possible a simplified syntax for parameter invocation:
<xsl:apply-templates select="*" interface="interface1" params="('string',
'str2', $variable)" />
Which is equivalent to:
<xsl:apply-templates select="*">
<xsl:param name="p1" select="'string'" />
<xsl:param name="p2" select="'str2'" />
<xsl:param name="p3" select="$variable" />
</xsl:apply-templates>
Regards,
Agnes Clarke
