[sv-ac] few new errata

Hi,
 
I have filed new errata in mantis:
 
1532: conflict in syntax of sequence events
1513: LRM does not clarify if class variables can be used in clock
expressions 
1510: inconsistency in action block syntax in the LRM 
1533: LRM not clear about types of local variables in properties and
sequences 
 
Thanks.
