That's not a private type, exactly... > How much flexibility do I have > in the type names... can I quote them? > > !!"some-uri".x Private names can contain anything whatsoever except for a '!' character. Public names are currently milited to IANA or DNS names. The above isn't a private type; using a URI means it is globally unique. However: !{http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd}p Is not currently legal. It also doesn't combine with our relative names scheme because it isn't an absolute DNS name. We could just add it as a valid type name, of course, and extend the relative type mechanism to recognize it: !{http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd}p - !.head - !.meta ... - !.body - !.p - This is the first paragraph... In fact we could drop our absolute DNS based scheme altogether if we did that... Or we could compine the two. This would require two things: - Use some other way to separate the namespace from the name (the {} is the way that many people write namespaced XML names - but it is just a convention). I suggest '|'. - Make the protocol and path optional; allow just a DNS name (we could say it is a shorthand for 'http:' and '/' or whatever). This would allow us writing: root: !my.company|invoice product: description: !http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd|p - 'A ' - !|em green - ' ball' to: !|client ... If there's no '|' at the start, an implicit 'org.yaml|' is assumed. If there's a '|' without any URI it is taken to be relative to the last explicit absolute space. > This would allow a full injection of XML into YAML. Remember comments, processing instructions, entities, CDATA sections... But I agree it is a good place to start. Have fun, Oren Ben-Kiki |

Remember that 'type' may contain any chatacters (except '!'), so writing "!org.cpan|Net::FTP" is a valid name under our rules. And a nice one, too - using '|' make it look so much better than using '.', and better expresses the intent. > | If there's no '|' at the start, an implicit 'org.yaml|' is > | assumed.

Well, I;m going over the syntax sectionm especially the transfer method, anyway - due to formats - so I could just plug this in... Have fun, Oren Ben-Kiki |
