+This should be read as saying that everybody can read all resources that match the pattern "*.acl" in the current directory, and for which this is an acl through wac:include chain from the resource's acl. (in this case this is a rule on acls)
+
+To allow all files to be writeable by the owner in this folder and sub-folders one could use
+
+```Turtle
+[] acl:accessToClass [ acl:urlPattern [  acl:base <.>; acl:match "**" ]];
+   acl:mode acl:Read;
+   acl:agent </card#i> .
+```
+
+assuming of course the user's WebID is </card#i> . 
+Note again that the `acl:urlPattern` gives a class that is larger than the class of resources for which this is true, as the only resources for which that rule is valid are those whose acls link to the acl in which this is written.

 The advantage of such a pattern language is that it allows the pattern to be relative to a resource, and so to be written out even for a client that does not know the full url of the resource.
