Subject: Re: [xsl] Should You Comment XSLT And If So, How? From: Steve Ball <Steve.Ball@xxxxxxxxx> Date: Thu, 20 Feb 2003 09:39:05 +1100 |
As you can see by the Subject line, I'd like to know if you think you should comment XSTL. And if so, How?
Of course you should! All software should be documented if it is to be usable and maintainable in the long-term.
Take a look at the XSLT Standard Library [*], which includes standards for stylesheet engineering. The method of documentation used is modelled on that used by the DocBook stylesheets [at some stage I have to take a look at Norm Walsh's XWEB for literate programming in XSLT].
XSLTSL documentation takes the form of namespaced elements at the toplevel of the stylesheet. Every (public) template is documented, with information such as the purpose of the template, how it is to be used, parameters and expected results.
One deficiency of this approach is that the documentation cannot be included inside a template itself. This was discussed last year (check the list archives). There was a suggestion to include an annotation mechanism in XSLT 2.0, whereas I suggested extending the whitespace stripping mechanism to also allow stripping of any elements.
HTHs, Steve Ball
