xsd - XML Schema for collection of components of any of defined type -

i have defined components of types inputtexttype , inputemailtype (their definitions not important here). need have components collection of number inputtext and/or inputemail, in order (example: text, email, text, text). i've tried:

<xs:complextype name="componentstype">     <xs:choice>         <xs:element name="inputtext" type="inputtexttype" maxoccurs="unbounded" minoccurs="0"/>         <xs:element name="inputemail" type="inputemailtype" maxoccurs="unbounded" minoccurs="0"/>     </xs:choice> </xs:complextype> 

but when validating xml

<components>     <inputtext>         <label>label 1</label>         <name>as</name>     </inputtext>     <inputtext>         <label>label 2</label>         <name>ghyyy6</name>     </inputtext>     <inputemail>         <label>drg</label>         <name>rgtght</name>     </inputemail> </components> 

i have error cvc-complex-type.2.4.a: invalid content found starting element 'inputemail'. 1 of '{inputtext}' expected.. xml correct (i need it). how should fix xsd?

for xml above changed xsd

<xs:complextype name="componentstype">     <xs:choice>         <xs:element name="inputtext" type="inputtexttype" maxoccurs="unbounded" minoccurs="0"/>         <xs:element name="inputemail" type="inputemailtype" maxoccurs="unbounded" minoccurs="0"/>     </xs:choice> </xs:complextype> 

and worked i'm not able define text, email, text, text first texts , emails.

move occurrence constraints xs:choice:

<xs:choice minoccurs="0" maxoccurs="unbounded">     <xs:element name="inputtext" type="inputtexttype"/>     <xs:element name="inputemail" type="inputemailtype"/> </xs:choice>
