Current limitations include: + * There is **no magical file name** like _aop.xml_ for the load-time weaver, + i.e. an XML configuration file for the compiler needs to be listed explicitly + on the command line. + * Scopes and excludes only affect method interception pointcuts, not ITDs. + The latter will always be applied and are unaffected by XML configuration. + * There is no global `<include within="..."/>` (see example above). + * Lists in aspect scope expressions are not supported, i.e. an expression like + `scope="A,B,C"` will be treated like `scope="A"`, using only the first element. + * If you want to apply a scope to an aspect extending an abstract base aspect, + you need to list and scope both aspects in the XML file. `-crossrefs`:: Generate a build .ajsym file into the output directory.
