[Feature]: Restrict symbols in names

[rly]

What would you like to see added to HDMF?

Currently, HDMF allows the creation of namespaces with names and version strings that prevent the namespace from being cached. HDMF also allows specifying names for groups, datasets, links, and attributes in schema (extensions) in a way that prevents generation of an API in Python and MATLAB.
Because of this, we have clarified the HDMF schema language to restrict the allowed characters/symbols in those names: hdmf-dev/hdmf-schema-language#43

What solution would you like?

Enforce the rules described in hdmf-dev/hdmf-schema-language#43

Do you have any interest in helping implement the feature?

Yes.
