RE: [EXI] Restricted Character Sets for Built-in EXI Datatype Representations

Hi Santhanakrishnan,

It is the restricted character set described in table 7-2 that governs the
encoding of integers when preserve.lexicalValues is true.

Patterns in schemas are taken into account only for types that directly map
into String datatype representation. They are string, anySimpleType, anyURI,
duration and all types derived by union.

Hope it helps,

-taki

Hi EXI WG
        In Table 7-2 "Restricted Character Sets for Built-in EXI Datatype Representations" patterns are defined for EXI Built-in
data types while encoding the values as strings. Consider the following schema

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:simpleType name="pattern_t">
 <xs:restriction base="xs:integer">
  <xs:pattern value="[3-4]*"/>
 </xs:restriction>
</xs:simpleType>
<xs:element name="RollNo" type="pattern_t"/>
</xs:schema>


In the above schema I happen to encode the type as string. For this I need to consider the pattern defined as per the table 7-2. But
what is I additionally have another pattern restriction as given above. Should I use the intersection of both the patterns to derive
the charset for the type ?
