[x3d-public] meta @name illegal value, X3DJSAIL regexp or ChemicalMarkupLanguage examples?

[Don Brutzman]

OK the regex constraint for NMTOKEN on <meta name="embedded whitespace"/> has been removed.

Similarly for MetadataString etc. nodes and CAD nodes: no strictness on whitespace or NMTOKEN.  The assumption is that the names for such metadata might come from a completely diverse set of sources; it would be unreasonable to have such content immediately invalid, or require special mangling of the name values (short-circuiting their value).

prototype, field, fieldValue, component, unit and HAnim name attributes all include the NMTOKEN check, because when values are defined (e.g. for humans) we are exceedingly strict in those cases.

This is all matching schema and DTD and tooltips.

Again thanks for identifying this issue during validation testing.

Document metadata is expressed in terms of name-value pairs, the name attribute on the meta element giving the name, and the content attribute on the same element giving the value. The name specifies what aspect of metadata is being set; valid names and the meaning of their values are described in the following sections. If a meta element has no content attribute, then the value part of the metadata name-value pair is the empty string.
