I'm not exactly sure what that sentence means.  Basically, the problem is 
that Web services are well-defined right now only for very simple 
interactions, such as the proverbial checking of a stock price or sending 
an order.  Most "real" interactions that people want to automate with Web 
services involve a number of interactions, with the exact sequence 
conditional on the results of previous ones.  For example, scheduling a 
meeting with a group of people or booking travel reservations entails an 
understanding of the "choreography" of Web services invocations.

The W3C waded into this because there are a number of partially-competing, 
partially-contradictory proposed specs and proprietary implementations of 
this kind of thing out there already.  One, known as WSCI (Web Services 
Coordination Interface?) was published as a W3C Note in June or so; that 
was followed by a proposal known as BPEL4WS that was *not* submitted to the 
W3C, apparently because (at least one of) the authors could not live with 
the W3C Intellectual Property Rights policy.  See the Charter of the new WS 
Choreography working group at http://www.w3.org/2003/01/wscwg-charter for 
more background on the technical problems to be solved.

The gist of the article is to note the split in the Web standards world 
between those companies and specs which operate under the RAND license 
model and those which operate under the royalty-free license model for 
intellectual property.  See the article itself and similar recent articles 
(such as those on the WS-Reliability spec that a number of companies 
preferring the royalty-free model proposed) for more on the politics and 
companies involved.
