param
The parameter (<param>)
element specifies a set of values that may be required by an <object>
at runtime. Any number of <param> elements
may appear in the content of an object in any order, but must be placed
at the start of the content of the enclosing object. This element
is comparable to the XHMTL <param> element,
and its attributes' semantics derive from their HTML definitions.
For example, the type attribute differs
from the type attribute on many other DITA elements.
