these nodes, in turn, has a one-to-many relationship to subnodes that have definitions
for individual types, resources, and variables.
An example of the XML for an environment with two user-defined types, two variables,
and one resource is given in XML example 2.
The System node (sys) is used to describe the set of main machines that are executing,
their instantiation, and the initial values of variables in the environment. The
core idea between the ”system” is a ”configuration”, which denotes a specific instance
of the machine templates and initial values in the environment. The idea is that those
”configurations” could be saved, named, and selected when doing simulation. In future
versions of the language, configurations could be extended to include concurrency semantics
and other ”selectable” behavior during simulation. The sys node has only one
children node that holds the list of configurations (the confs node). The confs node
has a one-to-many relationship with conf nodes that each contain a configuration definition.
Each configuration includes a name (the cname attribute), a description (the
cdesc attribute), and initial values for environment variables (the vinits node), and
machine instantiations (the minits node). The syntax tree is shown in figure 3.5 and
the tag descriptions are explained in table 3.6.
An example of the XML for an system with a single configuration is shown in the
XML example 3.
The Templates node (tmpls) is used to describe the set of machine templates that
are available to be instantiated in the system. The tmpls node has as many children
nodes as there are templates. There are three different types of templates - Main machine
templates, Sub machine templates, and Function machine templates. Each type
of template has roughly the same syntax, which are shown separately. The syntax tree
for the top level skeleton of templates is shown in figure 3.6 and the tag descriptions
are explained in table 3.7.
The different syntax for individual template types is explained in subsequent sections.
An example of the XML for a list of templates with 2 Main machines, 1 Function
machine, and 1 Sub machine is shown in XML example 4.
