Hello Yusuke We have been experimenting with EXI and find it an exceptional and efficient way to compress XML. We want to use it in sensor networks, where RAM and packet size is an issue. We hope to, within our effort to create XEPs for sensor networks, to include a XEP for EXI enablement of XMPP communication. If you want to join us in this work, you're welcome. Note to XSF members: Anybody interested in participating in such an EXI XEP, please contact me. Sincerely, Peter Waher

I'm wondering if it is possible to put EXI[1] with XMPP. During my experiment to encode some XML instances captured from my tcpdump to EXI, I have got unique particle attribution (UPA) problem as described in [2]. Although EXI works with schemaless XML, it's far better to use schema-informed EXI in terms of efficiency and validation. Schema-informed EXI is for valid XML, but current spec does not allow validation due to UPA. Changing local schema (suggested by Peter in [2]) breaks interoperability of schema-informed EXI. Is there any possible way to make a 'valid XMPP spec' with some (backword-compatible) specification update? I guess there are three choices. 1) change XMPP schema/spec to avoid UPA. This may break inteoperability. 2) use different XMPP schema for EXI communications. This looks awkward. 3) use XSD 1.1 for weak wildcard. I'm not sure XMPP community wants/hates 'cool' features of XSD 1.1.
