> Allow pattern restriction facet to be used on non-string types
> --------------------------------------------------------------
>
> Key: DAFFODIL-2877
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2877
> Project: Daffodil
> Issue Type: New Feature
> Components: Back End, Front End
> Reporter: Steve Lawrence
> Priority: Major
>
> Section 5.2 of the DFDL specification says that the pattern restriction facet
> can only be used for xs:string types. Daffodil currently implements this
> limitation.
> However, there are a number of cases where a pattern is the only way to
> correctly restrict the value of non-string types, such as xs:long.
> One example is a number that can only be between 100 and 300 but in multiples
> of 5. In that case, a pattern like this would work:
> {code}
> <xs:pattern value="([12][0-9][05])|([300])" />
> {code}
> Another example could be apartment rooms, where the first digit represents
> the floor (e.g. 1-5), and the second two digits represent the room number
> between 1 and 15 (assuming 15 rooms per floor). In that case, the pattern
> restriction might be:
> {code}
> <xs:pattern value="[1-5]((0[1-9])|(1[0-5]))" />
> {code}
> The patterns are often going to be a bit ugly, but in some cases it's the
> only way to correctly validate numbers using only XML Schema capabilities.
> Note that only supporting pattern on xs:string types is a limitation imposed
> by DFDL--XML schema allows pattern restriction on all types. We should remove
> this limitation and allow pattern facet to be used on all types.
