+## Topic: AOB?
+
+====
+
+Report on the ICU implementation status from TIM and MIH.
+
+
+### PR #718: [FEEDBACK] The data model could be simplified for declarations #718
+
+Merged
+
+### PR #728: Add Resolved Values section to formatting #728
+
+MIH: I don’t know if this PR touches how functions get “chained”
+We should specify the behavior, how options are merged (or not), etc.
+
+ECH: this was also discussed in the ICU TC meeting as underspecified.
+
+APP: please take a look
+
+### PR #731: Disallow whitespace as the first character of a reserved-body in a reserved-statement.
+
+APP: I articulated some principles on how we deal with spaces. But we allow “reserved” to treat spaces as it wishes.
+
+MIH: maybe should be addressed together with issue #635, “Some red flags with the current grammar for reserved-statement”
+
+APP: Also see #725, I think we have a model on how we treat spaces “outside of things”
+
+APP: compare #730 and #731, see which one we take to solve the ambiguity of spaces around reserved body
+
+### PR #732: Fix #726: remove :time/:datetime compose test
+
+Merged
+
+===
+
+#706
+
+
+MIH: currently ICU can’t both return a formatted value, and an error
+For example for this input : "Hello {$user}"
+
+If "user" is not available at runtime we can either return a fallback string ("Hello {$user}"), or an error.
+But you can't do both.
+
+EAO: This is an offshoot of #706
+
+APP: we should add the error names. And define behavior better. Later.
+
+### #586 Normative requirements for markup handling
+
+Move to LDML 46.
+
+### #711: LDML45 Acknowledgements List
+
+---
+
+Can we start discussion on data model changes now?
+
+APP: I would rather not make changes until 45 is shipped. Design documents, yes.
+
+TIM: I think that #718 should have a design document.
+
+MIH: I think a design document on the data model would be good, but only after we collect all the feedback from the implementations.
+
+### #709: Syntactic ambiguity with `identifier` production
+
+TIM: fine to close
+
+—
+
+Meeting next week, probably skip the one in 2 weeks (April 1)
