<!--

TODO:
|
||||
- Need to add regexp pattern for MIME media-type value of tEnclosure/type
|
||||
- Need to add regexp pattern for checking contents of guid is a URL when isPermaLink=true"
|
||||
- Need to add some form of constraint to check on an item that one, or other, or both of title and description are present.
|
||||
However, I'm not sure it is possible to represent these constraints in XML Schema language alone.
|
||||
- Need some way to enforce cardinality constraints preventing repeated elements in channels or items
|
||||
- Unfortunately the bug-fix for issue 10231 made this schema non-deterministic with respect to extensibility elements.
|
||||
We can't tell whether an extension element in tRssChannel is within the choice or after the item elements.
|
||||
Need to reconsider the solution to bug-fix 10231.

Date Revision Description
|
||||
31-Mar-2003 1 Initial version released for comment
|
||||
31-Mar-2003 2 Changes based on feedback from Gudge:
|
||||
- Remove targetNamespace="" and use elementFormDefault="unqualified" instead
|
||||
- Use namespace="##other" on <any>'s to create a more deterministic data model.
|
||||
- Added missing xs:documentation inside xs:annotation at the schema level.
|
||||
- Use xs:language for ISO Language Codes in <language> element.
|
||||
- Change guid to a single declaration. This loses some of the checking of the
|
||||
URL when the contents of the guid is a permaLink, so we will need to add
|
||||
that back in with a regexp pattern.
|
||||
14-Apr-2003 3 Changes to solve some element ordering problems.
|
||||
- Use xs:all in place of xs:sequence to support flexible ordering of elements.
|
||||
Although the ordering constraints for elements is not clear from the
|
||||
original specification, the custom and practice seems to be that
|
||||
element ordering is free-form.
|
||||
- Use elementFormDefault="qualified" for explicit intent.
|
||||
15-Apr-2003 4 Changes to solve some element ordering problems.
|
||||
- Use xs:choice in place of xs:all as previous usage of <all> was invalid.
|
||||
This creates the problem that insufficient constraints can be applied
|
||||
by the schema - for example, it can't prevent two title elements for an item.
|
||||
- Use elementFormDefault="unqualified" for to get the correct behaviours
|
||||
when importing and combining schemas.
|
||||
15-Apr-2003 5 Putting the extensibility element inside the repeating choice solves
|
||||
all problems with element ordering.
|
||||
15-Apr-2003 6 - skipHours and skipDays should contain a nested list of values,
|
||||
not just a single value.
|
||||
- Added version attribute to schema definition.
|
||||
- Corrected type of the cloud element
|
||||
25-Apr-2003 7 - Add regexp for RFC-822 date suggested by Sam Ruby
|
||||
- I had to leave the base type of the tRfc822FormatDate type
|
||||
as xs:string due to the problems with using
|
||||
a pattern with xs:dateTime described at
|
||||
http://www.thearchitect.co.uk/weblog/archives/2003/04/000142.html
|
||||
19-Jun-2003 8 - Fixed a bug that the Oxygen XML Editor spotted in the regexp for RFC-822 dates
|
||||
23-Jun-2003 9 - Added legal boilerplate license text for LGPL.
|
||||
- Minor formatting changes.
|
||||
24-Jun-2003 10 - Missing types for item/title and item/description - Spotted by Andreas Schwotzer.
|
||||
01-Jan-2008 11 - Copy made available under the Microsoft Public License (MS-PL).
|
||||
25-May-2008 12 - Bug fix 10231 from Ken Gruven - channel can contain zero or more items.
|
||||
06-Sep-2008 13 - Fixed tab-space whitespace issues. Now always use spaces.
|
||||
- Undid the fix for bug-fix 10231 since it made the schema non-deterministic
|
||||
with respect to extensibility elements in tRssChannel - need to reconsider the fix.
|
||||
08-Sep-2008 14 - Removed 't' prefixes from type names to improve class names
|
||||
that get code-generated from the schema.
|
||||
22-Sep-2008 15 - Move type def for rss element in-line for improved compatibility with Java 1.6 tools.
|
||||
01-Nov-2008 16 - Added the missing rating element from the spec to RssChannel.
|
||||
04-Sep-2019 17 - Fixed some minor typos in comments and messages.
|
||||
04-Sep-2019 18 - Use MIT license.
|
||||
04-Sep-2023 19 - Copied schema from <https://github.com/jthelin/rss2schema>
|
||||
- Fixed email addresses validation to support `email (real name)`,
|
||||
as in <https://www.rssboard.org/rss-profile#data-types-email>
