nigelmegitt has just created a new issue for https://github.com/w3c/imsc:

== Escaped % in schema causes some tools to error ==
https://github.com/w3c/imsc/blob/6a0bdfe5c5baf709c894d336af36cf2a66dca3d6/imsc1/spec/xml-schemas/imsc1-parameters.xsd#L32

has the regex: `\+?(\d*\.\d+|\d+)\%`

The final `\` before the `%` is unnecessary since in XML regular expressions `%` does not need to be escaped, and indeed it causes some tools (Saxon) to generate an error validating the schema. Omitting the `\` seems to have no harmful effects, so I propose to delete it.
