[ Lists Home | Date Index | Thread Index ]

Weird, this looks like the third time in this thread that I haven't received a
message that was sent to "xml-dev & Mike Champion".  So far I've [at the very
least] missed one each from Paul T, Michael Kay and Jonathan Robie.

PS: I know I should probably mail this to the list admins but I've misplaced
the original mail I received when signing up. :(

Once my power is secure, I will destroy all those pesky time-travel devices.
