/** Check whether the input stream is pointing to a valid list
of resource data elements.
The check is based on the size of resource data elements.
This means that a buffer can pass this check with non-existing descriptor Ids
that have a correct size.
A list of resource data elements can contain one unique resource data
element, without an end tag resource data. This is the case for
a FieldList.

data element. The stream is not
modified/progressing.
The stream must not be at its end.
