FW: [osis-core] osisWork regex in XMetaL

[Harry Plantinga]

Changing the escapes to ranges in the regular expression enabled XMetaL
to process it correctly. If you are interested in the details, see
below.

What he suggested worked, well actually what he meant to suggest. My 
current pattern is this:
(([a-z]|[A-Z]|[0-9]|_)+)((\.([a-z]|[A-Z]|[0-9]|_)+)*)?

It seems to accept the value Bible.KJV..1998 which Patrick said it 
should not accept. In the XMetaL help, the limitations for schemas are 
list as:
XMetaL schema limitations

1. Identity-constraint definitions are ignored.

2. Wildcards are ignored.

3. The <redefine> tag is not supported.

4. <import> of namespaces other than 
http://www.w3.org/XML/1998/namespace is not supported.

5. The instance attributes xsi:nil and xsi:type are ignored, and cannot 
be edited in Normal or Tags On view.

6. Checking an XML schema (.xsd file) for errors is limited in XMetaL. 
It is recommended that you use third-party tools, such as the ones 
available from the W3C web-site.

I'm not sure but maybe one of these has to do with why it accepts 
Bible.KJV..1998 even though it shouldn't.
