yes, canProcess shall return true only if appropiate, like the parameter Ma=
p=20
having the required properties. As an example, most JDBC based datastores=20
checks that the db connection params are present, as well as a fixed value=
=20
identifier that allows to avoid the clash (ie, dbtype=3Dpostgis,=20
dbtype=3Dmysql,etc)
