I've just implemented this in Jade. For the benefit of others implementing
DSSSL or XML here are the details:
- I recognize the PI anywhere in the prolog (so you can put it an external DTD).
- When there are multiple such PIs, I give the first precedence.
- I allow any of text/dsssl, text/x-dsssl, application/dsssl and
application/x-dsssl for the type. The type is case insensitive.
- I recognize <?stylesheet as well as <?xml-stylesheet.
- The contents of the PI are parsed like a start-tag. In particular the name
of the PI and the names of the attributes are case insensitive.
- The value of the HREF attribute can have the form foo.dsl#bar to indicate
the style-specification in foo.dsl with id bar.
- If the value of the HREF attribute is relative, then the storage object
that contains the PI is the base.
- After the removal of any #id part, the value of the HREF is treated like a
system identifier. So it can be an FSI as well as a URL.
- If there aren't any processing instructions I fall back to using the
document system identifier with the extension changed to .dsl.
I've also implemented a simpler alternative:
I also plan to implement something to allow catalogs to be used as an
alternative to PIs, but I haven't decided what yet.
