[xwiki-devs] [Proposal] Add "always on this page" value for SSX "use" property

Hi! I was wondering if it's OK to add a third possible value for stylesheet extension "use" property, something like "always on this page". This could also be the default value. As far as I know, the two possible values for SSX "use" property are: - "on demand" - which means that any page can demand that SSX - "always" - which means that all pages will have the CSS for that object While these two properties are very good and practical, there are some minor aspects: 1) Somebody (perhaps a designer) can create a SSX and other users (perhaps content editors) forget to "demand" it 2) Having a SSX with use="always" and a second SSX with use="on demand" both on the same page makes the two objects available for all wiki pages (in term of client side CSS) 3) The content is aware of the design. It's ok if in the content of a wiki page we can demand the stylesheet of another page, and that we can create some stylesheet that will be used by all wiki pages. But, in my opinion, the content must not be aware of it's own design. This third value ("use"="always on this page") will also help other projects like XOffice and XOO. At this moment, XWord, for example, should follow these steps: - save the page first (you can't create a SSX on an unpublished/nonexistent page) - identify saved page syntax (XWord works with XHTML) - "know" how the SSX macro looks-like in page's syntax (yeah, not a big deal, but it's something that XWord shouldn't care about) - edit the content to insert the $xwiki.ssx.use($docFullname) - publish the page, again "Always on this page" (or "always on parent page") usage could improve some of the aspects mentioned above. Any other solution is welcomed. What do you think? Thanks! -- Teofil Achirei
