# simpletype

When I start a project, its useful to be able to validate against XML

Schema primitive datatypes, without having to fully drink the XML

Schema koolaid.

By using a [schematron](http://en.wikipedia.org/wiki/Schematron) wrapper and a simple `st:type` attribute in my

xml I can achieve simple type validation as well as provide good

abstraction for any future validation (be it schematron asserts or XML

Schema).

This can probably be characterised as a 'tactical' approach to

validation .. I am fully aware of

[NVDL](http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CCIQFjAA&url=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FNamespace-based_Validation_Dispatching_Language&ei=IqlNUIiHKs3IswajrYCADg&usg=AFQjCNFIkNLDK-jtAgeGr8dx0_dcPgwyVQ&sig2=B6M5nSR7p0xZawDvbSSexA)

and the goodness of [XML Schema

v1.1](http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CCoQFjAA&url=http%3A%2F%2Fwww.xmlprague.cz%2F2012%2Fpresentations%2FWhats_new_3.0_XPath_XSLT_XSD_1_1.pdf&ei=tqdNUMyQIIrLswaWgoGACg&usg=AFQjCNFkn0VVtYHo7WyVxZ05wQFDHZHuYA&sig2=RHh_2_vwUDquW0J0bDcXhQ])

but every once in a while this approach suits me.

Schematron simpletype schema takes advantage of 'castable as' idiom;

```

      

    

        

            not a xs:string

        

        

            not an xs:integer

        

        

            not xs:boolean

        

        

            not a xs:decimal

        

        

            not an xs:float

        

        

            not an xs:double

        

        

            not an xs:duration

        

        

            not an xs:dateTime

        

        

            not an xs:time

        

        

            not an xs:date

        

        

            not an xs:gYearMonth

        

        

            not an xs:gYear

        

        

            not an xs:gMonthDay

        

        

            not an xs:gDay

        

        

            not an xs:gMonth

        

        

            not an xs:hexBinary

        

        

            not an xs:base64Binary

        

        

            not an xs:anyURI

        

        

            not an xs:QName

        

        

            not an xs:NCName

        

    

```

To use in your xml, just declare the `st` namespace and apply an

`st:type` to an element.

```

    1a2 watch spot run

    12

```

The limitations of this approach is that you are not applying types to

attributes (fine with me).

## Using

First you must [install schematron](http://www.bentoweb.org/refs/TCDL2.0/tsdtf_schematron.html)

To demonstrate run schematron, validating tests.xml with simpletype.sch
