Hello www-voice,

In 7_2.txml, assertions 340, 342, 347, 349, 366, 368, 370, 373, and 1186 
test the following features in <dialogstart>:

(1) The src, type, namelist, maxage, maxstale, enctype, method, and 
parameters attributes MUST NOT be specified in conjunction with the 
prepareddialogid attribute.

(2) If the prepareddialogid attribute is specified and any attribute 
values conflict with the values specified in the <dialogprepare> element 
this MUST result in the throwing of an error.dialog.notstarted event.

------

We believe that the incorrect combination of mutually exclusive 
attributes in (1) should be handled according to 9.5.1 Fetching & 
compilation errors:

"Errors that occur in trying to load and compile a CCXML document, such 
as ... validation errors (Including checks for mutually exclusive 
attributes...)"

Therefore these errors should result in error.createccxml or error.fetch 
instead of error.dialog.notstarted.

------

Thus (2) could apply only on the connectionid and conferenceid 
attributes. However, the Specification states in description of these 
attributes:

"If the dialog was previously prepared using a <dialogprepare>  element 
with a connectionid  or conferenceid specified, and this attribute is 
also specified, execution of the <dialogstart> MUST fail with an 
error.dialog.notstarted event."

Therefore the conflict in (2) cannot occur because it is not allowed to 
use connectionid / conferenceid in both <dialogprepare> and <dialogstart>.

We recommend to remove the statement (2) from the specification (Section 
7.2.2.1, paragraph 4).


Thanks,
Petr
