contain the term? (ODF 1.2 Part 3 Draft 12)

Dear all,

We are told of a package (PD 1.4):

----b
It may contain files whose relative paths begin with "META-INF/" and
whose names contain the term "signatures".
----e

* Does this mean that these paths must contain the substring
"signatures"? ("term" is an odd word here).
