305- Thetrickiest part is the `` $attributes `` variable. Because you canuse the
306- same tag many times on the same service (e.g. you could theoretically tag
307- the same service 5 times with the ``acme_mailer.transport ``tag), `` $attributes ``
308- is an array of thetag information for each tag on that service .
305+ Thedouble loop may be confusing. This is because a service canhave more than one
306+ tag. You tag a service twice or more with the `` acme_mailer.transport `` tag. The
307+ second foreach loop iterates over the ``acme_mailer.transport ``tags set for the
308+ current service and gives you theattributes .
