Close: I believe the correct term is built-in template rule. Your example is an instance of something I also find untidy: the need to trigger a given template in any of a number of modes. Yes, I know the trick of using call-template, but that is also untidy for small templates especially with parameters. Which brings me on to the other oddity: that while the built-in templates pass on the mode, they do not pass on parameters. I can see the rationale in the context of an environment using templates from different authors which makes use of defaults for parameters: but that problem seems to be small compared to the bad interaction with default templates. The language could be changed in a compatible way, e.g - a new attribute 'modes' on xsl:template which takes a list of modes. Meaning: exactly equivalent to replicating the template for each mode. (You can allow mode='' to be given to include the default mode). - a new attribute 'use-current-mode' on apply-templates and call-templates. Meaning: if 'yes' then same as mode="whatever" in the replicated copies above. Default 'no'. - a new attribute 'pass-parameters' on apply-templates and call-templates. Meaning: if 'yes' then same as providing the necessary with-param elements to pass the values of all parameters declared on the enclosing template which had values. The effect is recursive for any built-in templates invoked by apply-templates. Default 'no' Anybody else thinking along these lines? I have to confess I did not check the XSLT 1.1 stuff before I wrote this, so I'm prepared for the answer 'we already thought of that'. Indeed I would be surprised if this is not the case.
