Good catch. I guess that this is a remnant from an earlier
approach.

Our student Matthias Dettling actually found further inconsistencies
related to QSPEC presence in QUERYs.

Section 5.1.2.2 states:
 QUERY messages MUST always include a QSPEC.

Section 4.3 states:
   To make a receiver-initiated reservation, the QNR constructs a QUERY
   message, which may contain a QSPEC object from its chosen QoS model
   (see Figure 8).

So _may_ is not appropriate here since it MUST contain a QSPEC.

Furthermore in section 5.4.2 is written:
   If the QUERY
   contained a QSPEC, it MUST be passed to the RMF where it may be
   modified by the QoS Model specific QUERY processing.

The "if" is clearly wrong since a QSPEC MUST be included and
I guess that the sentence is a duplicate of the earlier statement in the
third paragraph of this section:
  When a QNE receives a QUERY message the QSPEC is passed to the RMF
  for processing.
