each realm can have such a file, whereas it is optional, whereas a 
warning is logged nevertheless if a realm does not have one

this is what's happening in the "from scratch realm". The general chain 
of responsibility is as follows:

URL: http://127.0.0.1:8080/yanel/REALM_ID/foo/bar.html

and then Yanel will first check if a 1-to-1 mapping exists

SRC: REALM_HOME_DIR/res-configs/foo/bar.html.yanel-rc

and if such a 1-to-1 does not exist, then it will check for matching 
patterns within

SRC: REALM_HOME_DIR/res-confgis/map.rc-map

and if no pattern exists, then Yanel will use by default the "file" (aka 
"node") resource type

no, you should replace the rti "file" within

src/realms/from-scratch-realm-template/res-configs/my-global.xsl.yanel-rc

by your own resource, because this is where the actual switch of the 
XSLT is happening

that's exactly what your resource should be doing. For example the query 
string could be something like

/foo/bar.html?xslt-version=2

which your resource would read from the request (if set) and then set it 
within the session, such that you don't always have to
attach it to all following URLs. And then your resource would for 
example build the location dynamically

/app{$xslt-version}/xslt/globals.xsl

instead reading it statically from within

src/realms/from-scratch-realm-template/res-configs/my-global.xsl.yanel-rc

as the "file" resource type does. (or something similar along these lines)

I think you are very much on the right track, except which resource type 
to replace (as described above)

Hope my comments help, otherwise please ask again.
