Naming conventions can be found here: http://wiki.ros.org/Names
1.1.1 Valid Names
A valid name has the following characteristics:
First character is an alpha character ([a-z|A-Z]), tilde (~) or forward slash (/)
Subsequent characters can be alphanumeric ([0-9|a-z|A-Z]), underscores (_), or forward slashes (/)
Your name starts with a "/" and then consists of alphanumeric charactes, so it's a valid topic name.
The first character is a forward slash, which is a valid first character. (And I can create a publisher for this topic without problems or warnings.)
