Open issues

+ #369 Namespaces in test catalogue still point to GitHub

Norm: suggests changing the namespace to http://invisiblexml.org/NS/test-catalog

john: what about https: ?

Agreed to use this namespace as http:

ACTION: Norm to look into possible other namespaces in the test-suite (such as Michael's)

+ #368 Add a symbol for "epsilon", don't allow absence of a symbol to be epsilon

https://codeberg.org/InvisibleXML/ixml/issues/368

Norm: I'm strongly in favour of this to avoid error issues such as Nt | | Nt

Bethan: we can't use anything that is a name. We could use the empty string ''

Bethan: It matches 'nothing'

Norm: we don't permit empty strings at the moment

John: define '' to parse as a term epsilon

Some discussion about where it goes in the grammar

Some (slightly heated) argument about whether epsilon could go inside character classes

ACTION: Bethan to draft a discussion document

Modularization

Norm: I've been working on a document on use-cases for modularity. Any new ideas welcome. Hope to get something ready for next meeting

Ambiguity

Bethan: needs some category in the issue/PR space to collect those relevant to various types of ambiguity
